Anyone done heads on a 4.8/5.3l nnbs?
I am curious if anyone has done them.I am thinking of going with a tr220 cam,but didnt know if i should get the heads done as well or buy new ones that are already ported with new springs etc..Mine came with 243 casting but arent they detuned some way with smaller valves.I would like to run a stall too.What would you guys reccommend.Thanx peeps.
