Using permatex grey gasket maker, and I'm using it on base gaskets, intake gaskets, and head gasket. I had put a thick coat on my base gaskets and when I took the head of it had oozed over and covered some of the airflow... I think that could have been the issue.
I like gasket sealant because it eliminates airleaks, so I'm still going to use it, but a much much thinner layer. Going to give a go at widening the exhaust port while I'm at it, and then do a test with my hi hi comp head vs my touring head. I have a feeling that might have it running better
