the 440-1's are a max wedge port and I dont want to go that route for several reasons, no max wedge intake manifolds that fit under my hood, and wont -1s move the power up into the upper rpm's I I try to shift by 6/62k rpm.

from what I have figured the chamber on the Indy S/R will give me 11.2/1 compression with a .039" gasket. if I went to a thicker gasket it would be less, but Im fine with 11.2/1
The thing I like best about the S/R is the room to grow in the future.

But... the CNC Eddie/Stealths seem to have as good a flow number between 200-600" lift as any of them.
