 MustangWorks.com: The Internet's Ford Mustang Power Source!
The heads that I'm specifically referring to are the TFS Twisted Wedge heads with their rotated intake valves, the TFS "Street Heat", Dart & Avenger heads with their moved valve locations (in different directions), and the TFS & Avenger heads with their raised exhaust ports (.750 &.400 respectively).
Street Heat heads are really suited to at least a 10:1 compression 302 C.I. engine shifting at 6500 rpm, and as with the other heads, with porting (and/or larger valves) can also make maximum power in larger C.I. applications.
The first thing that you need to understand about cylinder heads is that flow is not the "end all and be all" measure of cylinder head efficiency.

 Locust Enthusiasts Club
The later 711M model cross flow units all use a completely flat head design and in fact have larger diameter inlet valves on all except the 1300GT version which, along with better porting, means the later type cylinder heads are most definitely superior to the earlier ones.
The cylinder head was changed to have the carburetor on one side and the exhaust on the other, the mixture went in one side and flowed out of the other across the cylinder head at the same time the capacity of the larger engine was increased to 1600cc.
The next step after that would be to incorporate the 1300 GT camshaft and this, in conjunction with a big-valve cylinder head for optimum flow, will raise power output to somewhere around 80-82 bhp.

 Crossflow 200
With the US style integral log head, a 200 ci six will grudgingly yield 200hp, if you go to great lengths to adapt big carburetion, do a lot of porting, run lots of compression, and pay close attention to quench, cam and other details.
The Aussie Crossflow engine is a big leap over the US design, but in order to use the aluminum Aussie head, you had to use the Aussie block with it's unique bearings, seals, gaskets, timing set, and tin.
Some have found that the ports are perhaps marginal for the 250 cube engine they were originally designed for, but a close look shows that even in stock form they are optimally sized for a 200.

 MacDizzy's Cylinder Mapping Primer - Start The Process
This cylinder mapping section is for anyone who wants to understand these engines and the porting/systems surrounding them.
It can be measured before or after the mapping is done though it is probably best to do it when the head has been removed and the barrel is still attached to the lower end of the motor.
If someone performs the cylinder mapping procedure before and after the work has been done, it will be easy to find the changes.

Nigel Patrick wanted to bring the piston up above the cylinder deck height, but not above the height of the cylinder and head gasket, in other words, about 0.030 inch above the height of the cylinder.
Patrick decided that some head and manifold porting, a slight bump in compression, and a special Patrick Racing grind cam would definitely improve the peak performance for the motor.
The in-house lathe at Patrick Racing was used on the bottom of the cylinder (so the head gasket surface wouldn't be damaged).

 Port Matching
You can have the best cylinder head porting job in the world, but if the intake port leading to it cylinder head port does not match, you will not take advantage of the cylinder head improvements.
Port matching is the process of taking two ports and making sure they match at the point where they are connected.
Port matching is done by hand to ensure that the two ports align perfectly.

 The K series engine
It is unusual in its construction in that the engine is of 'sandwich' design, the head is not bolted to the block, instead long bolts are used which sandwich the block assembly together between an engine bottom plate and the cylinder head.
Considering that the same valve sizes and similar porting are used on 1.4/1.6 and 1.8 variants of the K series engine, it is not surprising that the head in standard form is under-valved for the larger engines and has inadequate flow for high specific outputs.
The remainder of the engines specification needs to be in step with the choice of cams, the cam specification is the thing which most radically changes the nature of the engines power delivery, it is pointless having a very highly specified head and induction system if you are retaining standard cams.

 ECOTEC Power from GM
The GM team solved this problem by reinforcing the two problem areas with twin studs that threaded through bored machined into the upper structure of the head and jammed against the outboard fire-ring areas of the head next to cylinders one and four.
GM Racing converted the Ecotec to a multi-stage dry-sump oil system designed to reduce crankcase windage and thus increase power by scavenging oil and crankcase gases directly from the cylinder head and oil pan into a high-volume external tank.
GM Racing subcontractor Shaver Specialties dramatically upgraded the Ecotec head with significant porting and maximum size lightweight stainless-steel valves.

 SUPERFLYGIRL.NET/Two-Stroke MX Tuning Tips
Porting or tuning is a metal machining process performed to the cylinder ports (exhaust and transfers) that alters the timing, area size, and angles of the ports in order to adjust the power band to better suit the rider's demands.
A cylinder head with a wide shallow chamber and a narrow squish band (35-45% of bore area) and a compression ratio of 8 to 1, is ideally suited for high rpm power.
For example; a head with a wide squish band and a high compression ratio will generate high turbulence in the combustion chamber.

 Decarbonizing a Two Stroke Engine
Before we start, I would like to mention that by decarbonizing an engine (term that I will use) I mean cleaning the carbon deposits from the piston, cylinder head and exhaust port.
The amount of carbon deposits is determined by the oil/fuel mixture, air/fuel mixture, type and percentage of oil used, cylinder porting and fuel additives.
This operation is very important for a two stroke engine (especially used in flight) If the carbon accumulation is substantial, the deposits will start peeling and they may score the cylinder or piston.
