ProComp/Speedmaster aluminum heads

It's more of a what can we expect reasonably out of a pair of these heads thread? Are they going to destroy a motor because one didn't spend a little extra money?



Only if one of the cheap parts that go into making cheap heads fails. Do ya feel lucky. Lol. I am a budget racer but even on a budget I shy away from bottom shelf items. At 1000.00 to machine a block and balance an assembly, damaged parts, lost races, I just can’t afford it.
