I'm getting ready to pull the heads off my car today to change out the gaskets. While I have everything out im going to do some detailing/cleaning and finish hidding my wires, anyways what is the Part Number for the ARP Head Bolt Kit I need? Also, when I pull the heads off do I just loosen the rocker arm bolts and pull the pushrods out and then pull the heads? On the re-install do I do zero lash on the pushrods then go a half turn past zero lash when I'm retightening the factory rocker arms? Thanks guys.
