Ok so my motor I built didnt last long. Burnt a piston pretty bad. So I put together alittle junkyard b7 so I could drive the car to work. b1 block with b7 head. Reused a old metal 3 layer head gasket with a bunch of copper seal. Made my own oil pan gasket with a bunch of hightemp gasket sealer. I have a bunch of old head bolts. What I need to know is, how much should a TQ them down?
