I have a 2002 chevy silverado and i was wondering my 4.8 liter will take 350 heads and if that will help or maybe 305 heads.
My idea is to put 350 heads on and change the rockers to roller rockers and get some power out of my motor.
Any ideas?

 

Can anybody help me with my idea?

 

Hey,
I have no idea if that would work...Dont remember anyone trying it.
Id call a machine shop that you trust to find out.

Hope this helps
