OK, so the original powerhead is gone. I would just order the OEM plastic elbows, remove the existing heads, and drill/tap them for the elbows…. Use new head gaskets, the old head bolts should be fine provided no one has buggered up the hex heads or used excessive heat on them…. Just tell the new owner to use premium fuel, and mix the oil a little heavier than 50:1 recommendation….
