Best Stock BB Heads?

Every record that requires/required stock heads or when that's all that was available, so a lot

Record machines, especially as time has progressed are BIG DOLLAR cars. I have a set of eddy RPM heads that flow 345cfm. They weren't cheap. I can't imagine what it would cost to attempt to squeeze every ounce of hp out of a set of iron heads, not to menaiton the R & D and the failure yield involved.

And nowadays who would do that unless they were restricted by rules in a certain class? But back when that was "all we had" those heads did do the job. The record books are proof.

No way in heck would I run an iron head on something serious now. I will continue to run them on the street though, because all I ever build for the street is stuff to have fun with.......that is unless the cost to prep the iron heads gets too much. ....and that could happen quicky.
