I've used 'em on my 454/330 hp. last year.65 mph Bow Rider was pretty fast(22'Chaparral).They are a good deal.I bought them from Summit.Whoever supplies your cam will provide springs. Trying AFRs on my 540 project.BOB

Merc's new Hp525EFI uses them. They have a hard coating. But looks like you have to freshwater cool them. Wouldn't be suprised if there is a service bulletin on those heads getting cavation holes from the silicate in the antifreeze as it flows through the head.

Between the GM rectangular and the Edelbrocks I doubt there would be much differance but from the 330 hp ovals I'll bet it would rock!!!
