That is what people are telling you the leak most likely is.btwick wrote: ↑Sat Nov 27, 2021 1:08 pm The second issue could be the thin parts of the head gaskets where they meet the intake manifold as mentioned above. Mine go up to the edge of the head, but I didn't put sealant anywhere on the head gasket. It could be flowing out to the outsides of the heads there somehow.
Lightly smear some RTV on both sides of the ear/tip/top/point or w/e you wanna call them, of the head gaskets before install. If using MLS head gaskets add a dab at the tops of the tips since they are short.
Since you didn't use MLS head gaskets, when decking or cleaning up those spots on the heads or block they could now be low spots and no longer crush seal.
