Be carefull, apply it with your fingertip around the coolant passages, a little goes a very long way. 100% pure silicone from G.E., hardware store, non-high temp variety is what they have all told me they use.
I ditched the header gaskets and use only silicone. I used to use high-temp for the headers, but when my engines came off the dyno this time, I noticed they had used the regular stuff there too. I'm trying it this time.



I should probably add that this is done using the Fel-Pro competition head gaskets with the stainless steel compression ring, #1011 I believe is the part#
