    Too low compression, look at rings for proper end gap, look for broken piston skirts, Broken valve guides?

    new wiseco pistons, rings came with them. oil lines are all hooked correctly. have it running for a few minutes. oil getting to oil screen, oil pump check valve, overhead oil feed line, cylinder interconnecting oil line, oil filter, inner primary return line, oil pressure gauge.

    Check how the exhaust feels, Bet you have a blown head gasket, leaking to the inside of cylinder

    new head gasket with the pistons; compression would be bad wouldn't it? s&s 495 cam,
    springs can take a 550 the machinist told me.

    Trouble Heads(M SHOVELS) I would check the head for true lay it on a piece of glass, can you see light or does it rock? Better gaskets may be the answer, I have also seen broken valve guides do this tho they are usually noise y, Wish i was there with you I like a challenge and like working on trouble;e heads
