Intake perfect fit without gaskets.

...or have the intake surface of the heads cut...that way any non-cut intake will fit those heads.
Yes, that is a good option of course. I’m just wondering if there’s someone out there who did it and it failed. Mechanic friends tell me OEM’s have used Silicone only but I have always used a gasket even if cut out myself. That said I pretty much always use some kind of dressing, including g a thin spread of black rtv.
