Seadoo 4tec Aftermarket parts question, and valves question

[flabound11]

I'm putting a new crankshaft in a 2005 seadoo 4tec 155. First question, has anyone had success with WSM, Titan, or SBT, parts, such as valves, bearings, gaskets, timing chain, and bolts? Second question, given that it's a 155, are the valves in the 2005 a must change if the starting number is a 72?

Thanks,
Chris
