If it performs it is a winner.
In 2006 Darin stated the only Pontiac heads he did were the 455SD heads on Don Kennedy's Super Stocker in 1989. Reportedly set the NHRA record.
Years later he did Kauffman high-port heads and intake for Mike Semchee that won Engine Masters contest.

Darin did some work for Jim Robertson here.

Cool video by George Bryce, valve events and about intake/ exhaust flowbench numbers.
