Possible problems running oversize valves, 472 peanut relief pistons, MTS #15, Potter rockers.

When i install my MSD setup, it will be limited on the rev side @ around 4800-5000 rpm. There were no valve float with current unkown springs.

 

How can we help you get "KNOWN" springs for your project? Surely there must be a way.

what is the casting number on the head?

Funny that You mentioned the cousin theme, i actually have at this point one cousin (albeit twice removed) living in Florida. Seasonally, though, since hi is supporting his sons efforts of graduating univeristy in US.
