i did check those out actually! but then it occurred to me, if .040 quench is ideal, i know my engine will NOT have quench, but there IS that little area where the heads will hang over the cylinders on the very edge of the bore, and if i zero deck this monster (i know its useless without quench, but if i want to swap some RHS or eddie heads later on i can build it with quench if i want to) then i will only have .028 clearance on the very edge of the pistons, and that tight of clearance has me a bit scared, so i opted for the fel-pros....just to be safe. Id really hate to have a piston kiss the head. but thank you Abodybomber!
Also, would anyone out there have a program that can determine the octane rating for a certain engine combination? I cant seem to find one and im thinking its for good reason, seems the general answer ive seen is "it depends on the engine" well i have pretty rock steady plan for what i want to do, specs and everything, but cant find a program or way to get a general idea...ill be running 9.42:1 static and dynamic with a comp XE268 will be around 7.14:1 at approx 137.03 dynamic cranking pressure. open chamber iron heads @ 64cc's...this seems to be whats killing me but i have to make do with what i have. would a 180 degree t-stat be better for this combo? ive heard too many horror stories about kb hypers and detonation killing them and now im freaking out...haha
