| If i dont get them this time around, then next time. These heads will only be on for about 3-4 months then I will be installing a "upgraded set ". I wanna see what upgraded heads really do. The " Upgraded" heads will have the same cams and springs I have now ( JWT R4 or R4+) with the HD springs. Will also have 1mm OS valves, exhaust and intake port work. Might go with some Ti retainers too.
