will this work? intake gaskets

intake gasket is for 55-86 or whatever...
heads are 91 corvette L98 HEADS.

To make them fit, I trimmed the gasket on the top side to clear the ridge on the top of the center-bolt heads. Will this hold vacuum???

Also, should i trim my edelbrock intake manifold a bit so it clears also?
What the heck!?!!!

It doesn't look like you've trimmed too much to seal,check with Edelbrock about your manifold before cutting on it. good Luck,Hank
