just orered my new optispark from summit and just had a quesiton when in installing it. Does the opti come with a gasket or seal of any kind or does it just sit right on top of the timing cover??? or is it wise to add one?

 

no gasket for the opti, there is a o-ring on the timing cover for the splined shaft that that the mates to. if its not leaking, leave it alone.
