Re: BBC alum head recomendations
I can tell you the stuff that come out of "Thunderz" is just that, IT THUNDERZ! The things will work.
As far as CNC stuff, yes it works on some "generic" stuff, but it's not all that it's cracked up to be. I've been CNC stuff for 20+ years now.
Now as far as heads for this 496, I would look at RHS 320's or Race Flow Development Victor "small bore" Eddy's. I can tell you this, I would NEVER put the 305's on MY 498 as the things would stop at like 5000 RPM!
