Quote: Have you check the intake fitment without a gasket to see if the space at the top of the intake manifold to the heads is the same at the top and the bottom on all four corners, top and bottom If not you may want to do that, it is not unusual for the intake to not fit properly after the heads are cut and the block decked and so on. Some of the motors from the factory weren't close to being correct
i did check the fitment of the intake. sitting in place with no gaskets the gap between the manifold and heads was nice and even all the way.
i sealed the intake according to tim banning's instructions, so i'm hoping that is good. i'm going to check that this afternoon, and if i fire it up then i'll play with some of the other things listed here and see if i can track this down.
