Help with Cometic Gaskets
I am in themiddle of my motor buils, and about to put my rocker boxes back on. My question is, Hillside cycles sent me a Wiseco gasket kit that contains Cometic metal rocker box and rocker box cover gaskets. the insert from Wiseco says to "use gascacinch or similar product on all copper gaskets" do I have to use the sealant, i always heard that sealant is a bad idea. Also, the raised surfaces on these gaskets face up when installing..correct? thanks guys.

Using any type of a silicone sealant is bad as it could get in to the oiling system and all it does is plug stuff up.It never disolves so I will not use it on any surface that could let it get in to the oil system.In the case of the rocker box covers for a metal gasket you can use KW Copper Coat.It has been around for many many years and I have used it many times with good results.
