The heads I have are 1978 truck heads with the 194s. I can get a set of 1976 heavy duty truck heads with small valves (3927185). I was thinking these might work. Just still wondering about CCs and compression. Buddy of mine was saying it might drop compression to 7 or 7.5.


If it ain't broke, don't fix it, unless you're me!
