I am building a twin turbo 427 and my block has no provisions for the 4 extra head studs that are commonly installed in boosted engines. I purchased AFR heads that have the tapped holes for them and I would like to run them to possibly eliminate head gasket failure.

Does anyone have any information on a company in Orange County, California that installs these bosses or any pictures and tips on doing it myself. I work with many gifted fabricators/ welders that are capable of welding cast iron. I would like to see how other people have accomplished this modification successfully to give me an idea of how to install them. But, If there is a local machine shop that does the modification for a reasonable price, I would prefer to have it done by somebody that has experience with these installations.

Thank You For any Info.
