Hello all...I am looking for some direction. I received a complete but used cylinder works bbk(94mm). 5k miles on it. I am going to have the piston and cylinder checked out at a buddy's machine shop. There was contact with a valve. It is a vertex piston 93.97mm. If I can't reuse piston I wanted to order a JE piston because it says they can handle higher compression and i plan on using e model base gasket. Also, will the cometic gasket kit work on the cylinder works head? Any advice on a good write up for doing the installation myself? Any tips or advice to help me out? I already have a fcr39mx with a full yoshi rs2 which I installed a few months ago.
