    thinner head gasket wont go on right

    well i got my ski back from the shop and got the stage 1 installed and riva vortec sc impeller. they said the head gasket wont go on right they said. the valve was hitting the piston suposedly???? there was a knocking noise with the thin head gasket. they put on the stock on and it went a way.
    somthing sounds fishy to me, i guess we will find out when i bang the high rpms if its gonna hold up or not.

    my ski was in the shop because the sc clutch went out with a bang all through the engine. had to pull engine and go through it.

    what do you all think about this????

    i think that sounds real fishy. they don't have the cam timing set right.

    DO NOT run your engine like this.

    Afte reading this,,,your right,,,the cam is deffinately out of time. If I was you, I`d pull the head myself. If the pistons are dented in any way,,,they must be replaced. They will become hotspots and a hole will form right in that very spot. Not to mention the valves although maybe not bent, could have the face bent a bit and will ruin the seats.

    Can`t see it being carbon on the pistons.

    Did they install the RR cam chain tensioner? It is needed with the thinner gasket.

    No I have stock chain tensioner with thinner gasket.Only need that if you mill the head and do port work.I think they had the cam out of timing too.

    Head gasket

    I was the tech that did the engine work for Painkiller. the valves werent contacting the piston.... But i was have trouble with the chain tensioner slapping the chain. I replaced the tensioner, and the oil pressure regulator. then i checked the oil pressure at the head and it was within spec. when i would roll the engine over with the rear cover off the chain would go slack for just a sec then it would tighten back up. the only thing we could figure out was the riva racing headgasket. we replaced the head gasket with a factory one and the problem went away... Curious if anyone else has had any problems with the rr headgasket install?
