Intake manifold pulling oil

I tested the bolt length and they don’t bottom out before getting the intake tight, and they are the same length as the other intake bolts I previously had. I switched to the arp intake bolts for that motor.

The onot gasket I could get to seal before was the felpro ms90109 intake gasket, I used the calipers to check how thick that gasket is once it is crushed and it’s .046 crushed. I think Iv been needing the thinner intake gasket again since I got the heads ported I just never tried that one again because if you look that gasket up online the ports are too small but I used the caliper and they are off on the measurements online. The ms90109 gasket ports are 2.25x1.16 so they fit my ports almost perfect with a little bit of sand paper on a deemed to make them perfect so I’m going to try those again and let you guys know. If not I will try swapping heads back to the original sides and yes the dowels are still in the block for the heads to line up
