Question, I assume the stock 1/8" gasket was the open style? Since the intake is open with a divider.

Next time at the track with mine I'll try just a gasket, which will lower the carb a 1/2" and give me more room to raise the air cleaner lid with a slightly taller filter. As of right now in it's factory configuration the lid is only 1/4" above the carb air horn and that's not doing me any favors, and it's too close to the hood to do anything with it.

The gasket I used was a 4 hole...unmodified. I do have a even thicker open qjet gasket but didn't take it with me. The better 60ft but same mph is telling me I might of lost a little upper rpm hp. I only shift at 5300. Even on the highway flooring it from 60 mph to 80 ir felt like it pulled harder with the 1/2" spacer over the no spacer but that could of been my imagination. With the 1/2" spacer I was using a 1/8th " gasket and a thinner one. With the 11/16" spacer I was using 2 thin ones.
