Some time ago there was a paragraph or so in a Muscle Car Review on the difference that extrude honing made to exhaust manifolds. The test car/ engine was Dave Dudek's F.A.S.T Hemi Road Runner. What I want to know is who still does extrude honing for fellow V8 Board members? Thanks in advance for the help.
I had my Nailhead intake and heads done with the help of Carmen Faso. He prepped the heads, sent them and then finished them when they came back. At that time the Extrude hone had a website where they offered pricing on the different actions according to # of cylinders, matching ports, etc. I can not find that site now.
I'm not sure if Brzezinski Racing still does. They are not far from my shop and have been around for a long time. https://www.castheads.com/manifolds-carb/exhaust-manifolds/ Larry
Larry, Thanks very much for the referral. I left them a message today and hope to hear back next week.
