    So my tall port track elimator aluminum heads with the ta performance pink .060 thick gaskets started to get sucked in abit. I caught it early. I've usually used the ta grey gaskets on previous builds and never had that happen. Even after 3 seasons! I always use copper coat spray on both sides and the right stuff around the water ports. Torque to 35#.never even a leak. Well when I took this apart on my tomahawk engine the copper coat was still on the gasket but not sticky to the aluminum. Didn't have to scrape off anything. Whatever the pink material is, it doesn't adhere very good. I have another set but I'm debating on whether to use them. Don't want to do this until I freshened it up. I also have a set of sce gaskets that are black and sorta like the ta grey style. Let's hear how anyone else installs them. Thanks in advance.

    Dan, not that ive done many intake installs, but i use Edelbrock gascacinch on the gasket to glue to the heads before putting the intake on. I use The Right Stuff on the water ports, china wall, corners where intake gasket meets china wall as well. Torque 20, 25, 35 and finally 40 on aluminum heads. So far so good.

    Thanks for the reply. I was thinking about trying gascacinch again. Haven't used it since the older factory steel days.

    It’s best to adhere the gasket to the intake since if or when you have to replace it and scrap stuff off your working with the manifold on a bench, not leaning over a fender.

    Id like a O ring design to not have to mess with gaskets at all. Have no idea what would be involved other than the machining.

    Not been able to have my buick motor together long enough to worry about an intake gasket failure......but on the sbc and bbc marine motors I've been doing I use right stuff on both side of the gasket. It's messy to clean......but I know its sealed.....I use it around both water and intake ports on both sides.....I can deal with clean up rather than sucking a gasket, ot sucking oil around the gasket

    The pink material is strange for sure

    I have used clear silicone after wipes with thinner..vey thin...3m headliner spray.... weatherstrip adhesive....and gasacinch

    I've stacked the felpro ones after gluing them together also

    I think I'm going to try the sce black gaskets I bought at the national's acouple years ago. I have to open them up to match my ported heads anyway and they're really close now,less work. Using gascicinch also.

    O-ring material would be so cool around the ports like Ken Betts heads but all the O-ring material I have is bigger in diameter than the port wall thickness between the intake ports already.

    We're straying a little from composite gasket stuff, but I think we'd be talking 3D printed port o-rings and machining the receiving grooves, and the cost & effort to get there.

    The narrow port divider between intake ports wouldn't need to be sealed, just the pair of those ports, for instance cylinders #1 and #3. This is because with proper o-ring profile and machined groove, sealing could be accomplished with intake and head surfaces meeting metal-to-metal. Thus any minute leakage between the two ports would be moot.

    I’ve had that happen with other sealers, it didn’t dry or cure, usually if the stuff is old or has been left open.
