Hyd roller pushrod question
Will stock hydraulic roller pushrods from a Mark 5 or 6 big block engine work with a retrofit hyd roller cam in a 60's big block with factory aluminum heads?

The proper way to do it though is to check the mid lift point for proper geometry---they could work with stock height heads and valve tip length. The pushrod lengths are 7.575/8.525 for the Gen 5 & 6. For reference, the Comp retro's are 7.728/8.684.
