save your self a trip down, scroll up & look at my pic at the sealant of the bolt holes in the heads for intake,I believe none are blind. those holes go all the way thru & is why I put it on thereRocket989 wrote:What Pop said! IIRC, early SBF heads...some of the intake bolt holes weren't "blind", they went all the way through. Oil can wick up and out. Thought they were the center four though...I'll have to go down and look. I've got at least one set of C6OE heads and plenty of later stuff. Solution? Thread sealer on the bolts!! I've had the same thing, though again...more towards center! At the very front...opens up more possibilities...
John - those intake gaskets look like Fel Pro 1250's!!! They make a steel core version (S3) that won't do that!! Just from looking at the pic though!
And don't over-torque the intake bolts on a SBF! They go straight down...no sense startin' to pull the head(s) UP!
& I think that is what I put back on. but if my dad was here to tell you I could tear those up too,,,no problem
