Im getting my engine back together and have gotten to the front engine plate, but before I install it there are two round water jacket holes on the front of the block below the top of the deck that need plugs. Do theese take regular freeze plugs or are they a special order item ?, thier size is 1" and 1 1/2", the roadster factory only shows one plug in thier catolog. My gasket kit has two front plate gaskets --one has an irregular shaped hole to go over the front crank--what gives??. You always see the recomendation to put vasoline in the oil pump to help prime it,--why not just using grease??
