Scott replied the topic: RE: rcmk base gasket size?
If your RZ is anything like the half dozen or so I have been into thus far, they come decked already pretty tight at @ .020" from the factory.
Lowering decking further without re cutting piston dome your going to be to tight on squish. * Also going lower is going to extend the intake duration more which being @ 157 now is going to cost you torque, tho rpm will be even higher.
The numbers your at now 184/157 is IMO pretty spot on for a race duty boat .... Play with pipes of different volume and cone angles :good: .. you will be mildly surprised on the power band changes that will be discovered.
