Ok here is a much debated question. I have a 6 bolt motor, 10:1 Manley pistons, Kelford 264's, Eagle crank, Manley rods, balanced. I have two different heads I could use on this motor a 6 bolt or a 7 bolt, so do you guys think a High Velocity head like the 7 bolt is better or is the High Volume 6 bolt head the one that should be used in this build, I have both and need some advice. I am running a 1G TB, Wally 255, FMIC, FP manifold with a Holset HX40, speen density and water meth because of the compression. Thanks in advance for some much needed advice from someone that has been there and done that.
