[QUOTE="sonic blue l, post: 1495375, member: 5185"] well personally I went with max force pistons. no valve reliefs, no coating, no modification to piston tops. They do have a " better " top of the piston vs factory. I also run a colt stage 2 cam. I have valve springs. my block nor heads were never decked. ford head gasket. only reason why valve hit pistons is if head are decked, block decked, valve train issue, lifter issue. If set up properly there is no worry, if a lifter fails or your revving it too the moon then perhaps you should have the correct springs, or change your cam profile. (lifter failure you'd have to tear down anyway, so reliefs arnt going to help much) bottom line is id switch cam profile, shorter push rods, different lifters, thicker head gaskets, anything before cutting valve reliefs. unless of course its a race engine that you plan to tear down every season to inspect. (im talking a daily driver, which tows, one takes on holidays, etc) my truck also has zero haze. (it can get down to -40 here in the winter, my truck also starts fine cold, etc) now tuning, yeah I agree. But also if one cuts a valve relief at .010" or .100" could make a difference. I tune my own truck and and I also built my engine. (not bragging, just stating that I know exactly what was done to it) [/QUOTE]
