Basically leave the exhaust alone. = Leave the=20 splitters or not? The archives are a bit inconclusive here. In one post = Lynn=20 says to keep the splitters. In another he says the Pport is very = sensitive to=20 exhaust back pressure. I have some turbo housings I can take the insert = out of=20 and put into the NA housings if need be. 
 
Other info I have says the exhaust = should be ported=20 to Close 55 deg ATDC vs 48 ATDC for stock while leaving the exhaust = opening=20 alone.
 
Intake timing:
 
IO 80 deg BTDC
IC 60 deg ABDC
 
13 in intake length?
 
31 in length header primaries 1 7/8-2 = in=20 dia
 
3 in collector into = muffler
 
2 in dia after muffler.
 
7500 max power
 
5500-6500 cruise power running = LOP.
 
2.17 drive and a 68 in = prop.
 
Speed-fast hopefully.
