It's going in a sd 305tpi with S/R Torquer heads and 1.6 Roller rockers, and a TPIS base and runners.

 

Mike,
It should be just about right for your combo. since you're going to use 1.6 rockers, make sure you get valve springs and retainers to match your setup. Also, you'll need to check for clearance on the pushrods as they orient to the opening in the heads.

You may need to use a round file to elongate the holes - which turns the holes into slots, thereby letting the pushrods clear with the 1.6 rockers. Good luck.

good call
