Oh well, I used the hard gaskets that came with the kit, and did not torgue the intake manifold bolts down. I tightened them to what seems to be "tight". Is there any where to locate a larger but soft intake gasket? Is possible to make them out of gasket material??? My guess is no. I don't know that I understand what you were saying about the reason the harder gaskets are not the best to use. My guess is that there are still vacuum leaks, thus still hard to get to idle right. There are several places that sell tri carb materials, wonder if any would know of such gaskets? And what their recommendation would be? I'll check. Thanks - kip
