If you don't mind sharing, how wide is the seat and how wide are the other angles?

Thanks

Hmm, narrower than i thought. I kept exh seat a bit wider to help heat dissipation (.070)
And then I did the same for intake (.070) and the others were kept to whatever it took to put the seat (45) where i wanted it so the 30 and 60 vary from .030 to .07.

Am i on the right track or did i mess up?

Can you post a picture? I don't think I'am qualified to answer that question, .005 extra width on a seat I wouldn't think would make or break you.

This is the combo I use in my Chevelle. I?ve been working it at a few years and have it down to 330 in that body with automatic. I believe it?s 335-340 in Camaro/nova still
