Tough to do with "stock" heads. I attempted a set of "budget"/non welded 441 heads once. I still needed long valves and shaft rockers.

What rocker ratio is your cam designed for? Shaft rockers might be your only option.
I like your idea. If you have a bunch of upgrades to do for Stock, explore your options with a few more upgrades. You're never going to set the world on fire, but you need to run the index and avoid heads-up runs. Can you do that?

Read the rule book extensively..
Been an NHRA member since 1970.
In SS car can fall in L, M or N.
Know it can be a K/SA maybe a J/SA
Figured Shaft Roller for stability.
Would confer with John at Bullet Cam what would be best parts.
Just did not want to carve up a set of 441 heads.
They are not as available as in the past.
Hoping well prepared Stocker heads would be compatible enough.
Can a 2 bolt main block prepared for stock live in a Super Stock Engine.
Or do you need an aftermarket block and just start over..
