edelbrock cylinder heads

Yes, the Eddie's are good heads. Like everything else out there, they can be messaged a little to be better. IMO it's too much for a 318, OK for the 360. The aluminum head yields lighter weight and will tolerate higher compression without detonation.

The RHS is a great head for the money. If you have a local rule situation that requires an iron head, it would be hard to beat. The RHS would definitely be the better choice for the 318. It's a matter of price point, IMO.
