The Thiteks are so nice and well done that if I had the money, I would buy them.
The edelbrocks look nice. Might need to cut spring seat for dual valve spring.
I have seen the drag pack heads on Barton's hemi. Its just an Apache head with minimal amount of cnc work done in the ports. Barton said he made 840hp with the older .640 spec dp cam. The record motor was over 900hp.
I think the key to huge hp is spintron testing. David gave me a 15min lesson on spintron charts and Im grateful he did that
