what is the max cr can the mva heads take? also i put in a stage 4 kit for my softail custom it came with:
jugs
mva heads(i do belive)
10:5.1 cr pistons
58 mm throttle body
se race tunner
im getting 110 tq and 112 hp
is that bout right cause i talked to bob woods he says tw 408-6 cam will be better anybody have seggestions?

 

I did some tooling on my bike. Was a 96 bored to 103. I went with MVA heads and the 10.5/1 SE pistons. SE 255 cams. S&S true duals headers so no catalytic. Everyone I talked to said to stay away from the 58 MM TB. I've wondered about that decisions since.

Dyno'd to 94 hp with 103 tq. I believe my choice in cams has my numbers limited.

If your 58 mm tb works out let me know I'm itching to get one and try it myself.

Good Luck
