Hey everyone. I am slowly but surely starting back to offering custom porting again. Very pleased to have added the Straub Technologies Mayhem 18 degree cylinder head and manifold line. These beautiful castings make 18 degree builds affordable to the bracket and street performance groups. All packages come with quality parts and are available as cast, cnc by Straub or custom ported by me. All versions are hand blended and come with flow sheet. Complete top end packages are also available in hydraulic roller and solid roller with heads assembled, rockers, camshaft and lifters, manifold, coated pistons( flat top or dome) and rings. Other Mayhem heads will be added to the line. Just PM or call for exact pricing on your selection that fits your build. Pictured are porters castings.

I should have posted first that I am back porting again though it be a limited hours deal. I refuse to let my health issue take me from the thing I love doing as much as breathing. Lol

Just received Straub Technologies new 18 degree cylinder head and manifold offering in a porters casting to evaluate. The availability of quality pieces at a price bracket and street performance can afford plus make good power is very attractive to say the least. Thank you Chris Straub for including me in the group of testers. Pictures and my take will post next week.
