L89 Intake gasket/installation
Ready to install the 3x2 intake on my 69 L89. Car will be judged. What gasket set would you use? Would you skip the gaskets on the lifter gallery ends and use RTV to insure no leaks? Significant points lose? Where can I find the correct bolt tightening seq. Enough for now, thanks.

Can't speak to the side gaskets, but the torque sequence is shown on page 6-43 of your 1969 Chassis Service Manual. I use RTV instead of the end seals - prefer no oil leaks to the miniscule deduction.

The most correct gasket set from an "originality" perspective is the set that Paragon sells. It's also the original embossed-type gasket which I prefer. I also use RTV for the end seals. Done right, they'll be no leaks. You'll often get leaks with the OEM rubber seals for a variety of reasons.
Using the rubber end seals, including the ones supplied in the Paragon gasket set, won't get you full points, anyway. Judges look for the tiny "GM" embossed on these. Only original GM gasket sets include seals with this embossment even though the original GM gaskets were not manufactured by GM, but by Detroit Gasket, Victor, and McCord.In Appreciation of John HinckleyComment

Thanks, RTV it is. I would prefer to find a point or two some where else rather than have a leaking intake. Lynn SchwebachComment

Thanks Joe, RTV it is. I will find a point or two some where else rather than chance a leaking intake etc. Sometimes this quest for Top Flight needs to be tempered with a dash of practicallity. Appreciate the help. Lynn SchwebachComment
