I have Edelbrock Performer RPM aluminum heads #6025 w/ 2.02/1.60 valves. Do you know if FelPro ever sold the 1262 & 1250 intake gaskets together in the same package? I know I should have used the #1250 gasket, but think I may have put the wrong one on. The reason I ask is when I replaced my lower intake gasket due to a water leak in the rear of the lower manifold, I don't think I put the correct gasket on. Ever since I fixed the water leak I have excessive blow-by. I never had even a hint of blow-by before this manifold gasket change. At first it blew out the cheap cork valve cover gaskets, then I got better ones with the metal wire in the middle. The excess pressure then escaped through the breather on my oil filler tube. Oil spits out when the engine is at full throttle. The car still runs strong, even turned the same quarter mile times before and after this blow-by problem. Is it possible that the gaskets I put on did not have this crossover shield, therefore resulting in my excessive crankcase pressure? I'm going to rip the upper & lower manifolds off sometime over the next week or two, and hopefully will be able to see what the problem is once I take the manifold off. I was just hoping someone could confirm this for me??
