You're correct. Bottom part of the gaskets ( the bottom of the port ) made its way below the intake. Hence my vacuum leak. Both sides. Will do some dry fitting tomorrow.
Are you running a valley pan or splash shield.....if not those gasket will soak oil up like crazy too causing issues
It's a flat splash shield from aamp performance. The gaskets are TA performance composition intake manifold gaskets.
If you think the angle is wrong, and you suspect the bottom, go get some duct seal at the hardware store.. then place it at the bottom of the intake ports, cover it with oil so it does not stick to the intake, and dry fit the intake, with no gaskets... see if there is a thickness of it left at the bottom after you give it a light torque.. It will give you an idea of where your at. If there is a gap at the bottom, you then have the choice of removing the heads, disassembling them, and having the angle on the intake ports fixed, or you can angle mill the intake the match it. Be advised.. with a block/heads that have been excessively milled, watch to make sure the intake is not contacting the end rails of the block. this will hold the intake up, and when you torque it down, it will leak at the bottom. In this case the intake is warped, after torquing it down while contacting the end rails, and will need to be machined on the flanges, and the end rails, to get everything to fit. Now you know why I designed piston/rod combos that require very little machining of the block.. we have just scratched the surface of the issues that come up, when trying to fit everything back together after excessive milling to get zero deck.

I use a spray contact adhesive and apply to the head side of the gasket, wait for it to go tacky, then place it on the head then bolt the manifold down(not torqued down) then leave it over night and then spray the gasket to manifold surface, wait for it to go tacky then place the manifold down then torque it down..... done! Cheers
I had my intake off to change the roller lifters. Mine stayed in place. Looks to me like that gasket slipped before the bolts were installed. That points to a fit problem. Trial fit the intake without a gasket and sight down the bolt holes. Also do as Jim suggested to check the angles. If there is a problem, now it the time to fix it.
Not back together yet. Dry fitting now. Trying to determine the right intake gasket thickness I need. Angle for manifold/head is good.
Use a paint paddle on the China rails,...then makes sure the bolts go thru the holes in the intake nicely,..if so measure the distance between the head to intake flange with some feeler gauges,...add 20tho to that number and order the closest thickness
