If I purchase stroker kit 1 for my L67 can I still (swap) get the lower compression pistons for higher boost. (12-16 psi) Instead of the normally supplied ones?

The compression ratio available with the entry level stroker kit is around 9.0:1 While it's higher then factory, the fact that the engine capacity is being increased means that the boost pressure will drop due to the limited capacity of the M90 supercharger. Therefore the slightly higher compression ratio from factory (up from 8.5:1) works out well However, unless you had your heart set on going with a stroker setup, I wouldn't go down that path unless you were planning on upgrading the blower at some stage, due to the limited capacity of the M90 supercharger
