Many people want to make their 998 or 1098 a-series go a bit faster, but the 12G295 heads appear to be rather expensive. The alternative is to install a 12G940 head from a 1275, which is a wonderful head for the price (used of course). Problem is, that the exhaust valve hits the block, just a little bit. There are some ways to get around this. Sink the valve and use a standard cam is one way, but for any good performance one needs to use a high lift cam and pocket the block. This can be rather expensive as normally the engine must come out and sent to the machine shop. Another alternative here is to grind it while in the car... by hand?? NO, but maybe this tool I drew up would do it. Just use a bit of oily cloth in the cylinder to catch the dust and a 36mm face-mill and grind it by hand.

Would anybody like to make it and try it out? Then you can lend it to all us needy people who want to pocket our block.
