Re: Super Stock Hemi Head Tech
Hemi valves are 5/16, not much to take out of the stem. I do not think anyone makes or uses them, could be wrong!

Re: Super Stock Hemi Head Tech
Yeah I get that but we are now spinning these thing 9600-10000 rpm’s and the head is still big and heavy. We have figured out the bearings and oiling but the last 10 or so blow ups have been broken valves
