Default Which header gasket to get?

I need a a little advice. I'm getting ready to install my Exotic Muscle headers. I know I want to get the Percy's Seal-4-Good aluminum gaskets. I'm just not sure which ones to order.

The car's a stock 1988 L98. Are the square 1.5" the proper gaskets?

Heads on the '88 should be "D" ports I believe....I'd go with the round ones myself because you can always open them up. Check the gasket against the head before you bolt'em on.

If you like Percy's aluminum gaskets, you would love his carbon xxx ones.
I switched years ago and never went back.

Thanks for the replies, folks I'm having a friend with a few more tools (and mechanical aptitude) and a lift help with the install. We'll get everything unbolted and take a look to see what the best gasket to match up between the headers and the ports would be.
