1991 360?

The later roller engine did have a relocated pushrod hole do to the angle of said pushrod for the taller roller lifters.

The biggest downfall of the 308 head is the open chamber and the cracking issue. I have never seen a set used that didnt have them. If they are not cracked now, its only a matter of time.

Put a set of RHS heads on and be done with the old stuff and let er RIPPPP
