yeah, what vintage said. one thing to add about blocking the crossover. the 1205's are just gasket material over the crossover, and it will blow out in short order. if you do block them, what i did with my old heads is cut a piece of tin about 1/4 larger than the opening, smear a little red rtv on both sides of it, and put it over the opening. then just install the gasket and manifold as per usual. and as for torqueing, i'm pretty "torque happy" with engine fasteners, but i've never torqued a manifold either. i just use a short wrench, so you can't get too much leverage, and tighten all even, with my highly calibrated clicker wrist. that works for me anyway. good luck with it [img]graemlins/thumbsup.gif[/img]
