Makes sense. The heads I have are stock but the aftermarket heads that are stronger. Maybe I will have more work done to them eventually. For now I'm gonna do headers and the 1.7 rockers. What is your tire size and gear ratio?
Extracab 1/2 ton 4x4 3.92 17" 265
Has a shell ,but trans is built and gets into gear 'holding power'..as walt jr says.
I have some comp 986 dbl springs 135lbs seat and 265lbs @lift. Heads do 230's by .400 int and 204 exh...exh peaks around 218cfm. Peak intake flow is 263cfm @.550. Imo i could use different springs for sure.. but they work. When I say that I mean a higher rate with less seat. Fwiw I had the guides opened 11/32 and valve job done by Machine Tech in Oceanside CA. They do good. I did the added seat angles, chamber massaging,and porting and flow testing, spring seats,guide machining and assembly . I had Mesa Machine mill them .024
