When this post first stared I thought it was just an idea someone was kicking around that would never happen. A fun type of post that we sometimes come up with during the winter. But with the answers here and well within his boundaries it’s not only possible, it’s easy possible. And if you put his very first post and a couple others the blueprint is there.
Come up with with an aluminum magnum copy of a Speedmaster head cast in another country to keep cost down and slightly modify the pushrod hole moving it over a touch. I think the magnum style rocker simplifies this. He’s already planning on a 2.08 valve which is overkill for his 290 cfm target but would attract guys just wanting the heads. Now just come up with a “good” ported head to make a cnc program from which he stated would be done in America and add a street, street strip, or full race valve job and the needed spring package. The pan rail extension is a non issue on a fresh blueprint as would offering a couple different exhaust bolt patterns. The only drawback to this head in my eyes would be that for guys like me that has so much invested in the LA style head it wouldn’t be a viable option but a fantastic setup for his target group. Just to add something a simple tweak to his cnc program could take this 290 cfm head to a 325-330 or more if the material is there.
