Hi guys,
I'm getting ready to put my Dart heads on and was wondering what I should do about the Cometic head gaskets, I've read that some of you guys spray them and some use them dry. last thing i want to do is have to take them off again because of a leak. if I spray them what is best to use, heads are new and block is spotless..

It is up to you.
Personally I always spray them with copper gasket spray, I've used them several times with no issues.
Just lightly spray on both surfaces, let it semi-dry and bolt them on.

I installed mine dry. No leaks. The most important thing is clean, true mating surfaces on the heads and block.

Thanks for all the input guys,

I think I will spray them just for the added insurance. My block surface is prepped very well and the heads are new and have been milled .018, One end of one of the heads was out .002 but it was corrected when they were milled.

I can't wait to see how she runs with the Dart heads and FAST Intake.

I've built many race engines with them and I always install them dry w/o problems.
