Re: Heat insulation carb base gasket PN?
It depends on what you want the engine for??? If it's a street car, then it's low end torque you are after. That would require a 4 hole. If it's a track car, then it's top end horsepower you are after. That would require an open spacer. Either way, you should do some experimenting here. Some combos respond to 1" spacers where some get the most from a 1/2" spacer. You may require a 2" spacer to get the most from your setup. The only true way is to either dyno it with each spacer or do the seat of the pants test.
