Fel pro intake gasket
 

My heads are 2.020 intake and 1.600 exhaust. Which felpro gasket will fit the best. There's so frickin many to choose from

What color is the car? Does it have seats?

All humor aside, the size of the valves do not dictate the gasket used. It all depends on the cylinder heads you have, and in some instances, the intended intake manifold also plays a part. Also, if your heads have been ported, a gasket with oversized port openings may be required.

FEL-MS95580 would be the set I just used, looked quite nice for ported heads too. Or as mentioned above an oversized one if really needed.

If we are talking about a LT1 with AL heads....I prefer the "printo" seal ones

Are they aluminum heads and were the seats replaced?

The FelPro paper gaskets with the silicon bead I have seen delaminate if covered with a layer of silicone at install. the gray metal core ones I have never had any trouble with, and the stock plastic ones I have seen compensate for a huge angle difference on a friend's crappily machined 383.

The Felpro gray and stock plastic would be trimmable if the person who saw fit to jamb 2.02 valve in got carried away in the port too.
