Re: Mushroom lifters – Any advice
Ron, the Hanson head appeared early 90's as I recall. Machined out of a lump of billet. No water jackets, just solid. They were made for nitro burning drag motors. The fin design was inspired by a Navarro head, just cus it look pretty.
Don't know if there still available, of course, being solid any combustion chamber design is not a problem.
