There are significant differences between my head and an Edelbrock or a Pond. All good parts, but all with different intentions and targets in mind.

I will pour one of JDC ported Survival heads sometime today if I get the chance. I have a set here that he had at a similar 340+ cfm. As cast with a valve job and bowl blend mine are at 180cc. Not sure how far Joe took these but it does not look all that big.
