EQ Head?

[GARY C]

I have never found it wise to further restrict a restricted engine nor do I consider a few degree change in duration a goofy revised cam. The carb only becomes a restriction in the upper RPM range so you have to focus on low end power and a broad tq band and no I do not build these but I know plenty that do and some due to valve and lift restriction are still successful with 30* seats and goofy revised cam shafts.

Ok Gary, from your vast experience knowing someone that knows someone , you win, your right, I am wrong. OP, use a 30 degree seat. You should do really well.

[GARY C]

I would not opt for 30* seats If I had the option of a bigger valve but for the sake of argument Fshaft what have you found when increasing flow available to the engine?

Will probably be a 4.040 x 3.480 bore and stroke if that helps any?
