What is the best type of sealer to use between the block and the main cap on a mark IV big block? One of my manuals says RTV, the other says an anaerobic sealer like Locktite. Last time I assembled this engine I used RTV. No problems but it sure seemed thick. Happy Thanksgiving
Thanks, Keith

He, He!!

A daub of good old Permatex's "Indianhead Shellac Gasket Cement", imho!!

Darn messy stuff is made for this.
