Gen IV Big Block Head Gaskets
Guy's, Ive a question re the correct head gaskets for my 454.
It seems there are 2 style of block and gasket. Some blocks have 3 coolant holes on each bank, I believe all heads have them, and some don't. Gaskets come with or without coolant holes as you would imagine. My block has the 3 coolant holes but typically the gasket set I bought came without the 3 holes. I am taking this up with Summit because there was no mention if this in their description but that doesn't help me get the engine back together. I have been talking with a supplier here in the UK and the literature they sent me seems to indicate that I can fit a gasket with no holes even if my block has them, in effect blocking these coolant holes. So info on the web does seem to support this but whats the point of having the holes and blocking them off. I have to assume they are there for a reason. Maybe not, other info indicates that yes its nice to have them but they don't make that much difference. Does anyone have any experience of fitting the solid gaskets to a block with the coolant holes? Bill |
