318 Port match heads to Performer RPM Intake

A long time ago....in a galaxy far far away.....I port matched a set of 302's to sorta match up to a performer RPM intake (not pretty). Basically all I did was round off the edges a bit on the port so the air was not slamming into a wall as it entered the head....again, it was not ideal, but it ran OK for what it was. As you can see from the picture, the parts you selected are severely mismatched...best choice would be get a performer intake (which is a 318 intake), or get 360 heads and keep the Air-gap.......but since you said that is not an option, you can also just bolt it up and run it. It should run about the same as anything else on a stock-ish rebuild such as this.
