To shave or not to shave?
In the quest for evermore performance through compression ratio increases, has anyone out there machined a set of 3.5 heads more than the FSM specified .008 inch? I'm supposing that bad things happen between the valves and block or pistons if you exceed this limit. If it's been done, what's the max cut you can take?
As an alternative, if you can't cut the heads over the .008 inch, thats not going to make much difference in compression ratio, has anyone ever welded up the combustion chambers to decrease the volume and increase the CR? It's relatively easy to weld extra material in alumunum, and machine it into shape so the valves are not shrouded and flow is maintained. Anyone done it?
Thanks for any input anyone has.
