I purchased an intake from Enzo a while back that was one of 5 from a run of Blue Thunder manifolds. I tried putting it on my engine a number of times and was not able to get a good seal with the heads. It seems as though I keep getting an
oil leak on the underside from the lifter gallery. I was wondering if anyone had any suggestions or special tricks they had to use with one of these manifolds or might it be my heads. I have World Products cast iron heads.
I tried using Ultra Black RTV on both sides of the gasket one time and still had no luck. I also put a straight edge on the gasket surfaces and everything seems to be perfect.
Thanks, Jerry
