On the stock manifolds that is.

They are about 1 3/4" high, and at the narrow point the width varies from about 7/8" to 1 1/4". I think it opens up a little after that. They really put a lot of bolt clearance on there. I think I would have rather had tight clearances but bigger primaries! The walls are pretty thin there, I didn't try porting out the primaries.

I ported mine a little, basically just smoothed them out. I actually broke through one and had to have Al fix it. I think I am just going to stick with stock and send them to Jet-Hot. May not quite be long tubes but I doubt there is much difference from shorties.
