Good to know, I think I might have a couple sets of those heads. I live in North Adams, Massachusetts. It's in the nortwest corner of Mass, near the Vermont and New York boarders. There isn't anyone local to me that I'd trust to properly prep an FE head. I'd rather just send out a set of core heads and an intake to an experienced FE builder. Along with the head porting and valve work, I'd think hardened exhaust seats would be needed. Then to balance the port flow on the intake.
thanks,
Mark
