January 1st marks the exact date of CFM's 25th Anniversary. Thousands of heads and manifolds have come out of the shop over the years. It has been one heck of a ride. I hope to continue until I've totally destroyed my body and simply can't do it anymore. I started this business to provide quality, affordable porting to the masses. Taking my 6 previous years of experience, I jumped into entrepreneurship with both feet. Personal thanks to my uncle Jack Williams for providing shop space and business guidance in the beginning. He has helped me more than I can ever express. I want to thank all of my customers over these many years as well. I promise to continue providing the same great service as always. I may fall behind deadlines occasionally, but I'll get it done and make it right. May 2024 bring you lots of horsepower and many wins!

I finally got caught up on all my email. Sorry for the lengthy delay.

Brodix 2X heads. We kept the 2.300" valve and still got them to 420cfm with great airspeed. These heads now have 950hp potential on a big block Chevy.

Updated Profiler 210cc heads. They now go 335cfm at .800" lift. This set should break 700hp on their 421" small block.

Just got an update call from a customer. 355" small block Chevy, two barrel, .520" lift solid cam, circle track engine. Before and after test of porting the Dart Iron Eagle 215's. Head porting only with no other changes, the engine went from 432hp to 483hp. That's a 51hp gain on a very limited engine. Not too shabby!
