so what exactly is the differance between this and the normal 240 head? says needs race gas but doesnt say what octane? say i were to get one of these what would be some things i should keep inmind? do i need to rebuild more often? say i wanted to just use it once in a while would it just be as easy as changing the head, jet and gas each time?
how much extra power could i expect from this?
