I continue the build of the stock 2.0. Reading the engine build book and the Raby video, both refer to arrow markings on the top of the pistons for orientation. However, these new pistons from AA do not show any markings. I have an email into AA, and searched here, but can't seem to find the solution....
The valve relief grooves go toward the bottom as the valves angle upward from below.
Def check your deck height with those AAs. On my rebuild it was excessive (.070) without a shim. Switched to KB pistons and they were right on the money at .040....
AA really needs to put a notice in the box or on their site. I have seen this question sooooo many times on the different message boards.
