The 292 I will be building came out of a 62 galaxie and I heard the valves got smaller in 1960,I am building a basicly stock motor for torque so are the 60 and up heads really that bad so other then smaller valves are there any other major changes done to them. Since I am not building a race motor and if I cant find a set of G heads locally would the 55 power pack or C heads do me just fine if the 60 and up heads are not worth using.

Butchering up everything I can get my hands on in Dayton Ohio
