Need some help here, I have a GSR with nolt ons and purchased the Blox B's with skunk valvetrain. Have all basic bolt on mods. Need info from people who have the Box B's specifically in stock blocks. I am considering milling the head, but my motor is pretty strong right now. It is stock but pull 245psi compression through out the cylinders. I also have skunk mani to help out.
Thanks in advance
