There were two designs of Ford Pro Stock cylinder heads built; the mirror port head and the sequential wedge head. Darin designed and built the sequential wedge cylinder head for the Ford Pro Stock class platform. The belief by many is that the new cylinder head would have given the Ford engines the power to run against the GM engines.

Darin and Ford submitted the head to Glendora for approval and after having the cylinder head in their possession for some time and sharing it with other teams and cylinder head builders, it was rejected.
Two prominent Pro Stock engine builders that I know also told me that many of the features of Ford's sequential wedge head were incorporated into the current version of GM's Pro Stock cylinder head.
