    Anyone have flow numbers for Bowtie heads? My dad has a set of these that are mildly ported and shaved down. Hes thinking about building his 69 Firebird up and I want him to take those Bowtie heads off of his Circle track car and put them on a nice 350 for the Bird. Would like to run Desktop Dyno numbers and see what a good setup would be.

    nobody has flow numbers for ported heads, your local machine shop or performance engine shop should be able to help you by bolting them up to a flow bench.

    which "Bowtie" heads do you have? in the current GMPP catalog there are 3 "Bowtie" heads. a Phase 3 Bowtie, a Small Port, and a Large Port Vortec Bowtie heads. i can only assume there is a Phase 1 and Phase 2 Bowtie head that was once available.

    I was more looking for stock flow numbers. Can't locate them. Hopefully I get them on a flowbench sometime.
