I'm going in the engine. Would like some opinions on the performance of heads. With some reliablility in mind. I dont mind wrenching, but would like to at least go 20k before some maintenace. Looking at my MVA heads with Baisley corrected Geometry with raised intake and 30° perimeter dome. Or the S&S B2 or a better head??? Baisley will be more expensive however I have put a limit of 4k on just head work and heads. So I guess I have some options.
Engine is all-bore 114, 4.1/4.2 bore D&D Boarzilla
Looking at 7000 RPM
I ride 2 up 30% of the time
The other 60% is bar hopping with no drinking. Or just putting around low rpm, granny shifting.
10% long rides about 500 miles one day.
Will be professionally tuned
