Does anyone know what the correct torque for the head bolts on a N/A should be using a stock style ceramic head gasket. I just replaced a head gasket for a friend and it seems to be leaking ( white smoke coming from the tailpipe constantly). It's a N/A so I used an extra stock head gasket I had laying around but had the head machined smooth for a metal gasket but he is on a budget so I went with the stock style gasket but I torqued it to 75lbs like a metal gasket, could I have over torqued it and smashed the gasket. It's the only thing I can think that would make it smoke like this as soon as I put it back together. Any Ideas, Thanks.
