Squish for 2008 DRX90

[mfr440]

Can someone tell me where to set the squish on a 2008 DRX90? It's all stock with the factory high-compression head. We put a new piston in it and the piston is hitting the head. We want to make sure we put the right combination of base gasket(s) in.

There are threads for 50s and 70s, but nothing for a 90 that I can find.

Thanks!
