70Wcars runs 10.5 on iron heads....but they aren't J's!

Ebrocks come bare and, out of the box, they don't flow any better than iron big-valve W30 heads. Sure...you lose 80 lbs or so, but at what cost on top of the jack for the heads?

As Joe suggested, I'd find earlier iron heads and spend that Ebrock head money elsewhere...unless you are really building a racer or boulevard bomber.

Just my $0.02.
