When you're only looking for another 1/8 of an inch it's sometimes easier to find .040" in three places. Consider milling only .040 or .060 from the carb pad on the new intake - nominal if any impact on carb mounting or performance. Thin carb .030 gaskets are readily available - lots of guys normally run the nicer thick ones, but they are .060 or more. Air cleaner gaskets are the same way. The plastic/foam uppers and lowers on air cleaner elements are ripe for trimming with zero impact on filter sealing or function. There have been more than a couple cases where I found a cheap, quick and easy 1/4 inch or more for guys with combinations that "did not fit"....
