Edelbrock RPM porting...opinions wanted..long

I am finally getting the ol boy together. Took some time and laid out all the ports on the intake. Dye, blue, scribe the works. So after it's laid out here is what I see: Roof matches spot on, sides could lose 1/8" per side, the floor floor could lose 1/4". Thats what it would take to match the heads dead on. IF I did it I would keep floor up an 1/8". My conundrum is looking at the intake I think that much off sides will get close to breaking into the push rod tubes. Also it appears to me it will be more bellmouthing than blending/opening up. I read up on an old post that Joe C worked one over and have Jays book. Curious if the work would work and how much fruit is in the labor...from those that have done it. Research indicates mixed results. Let's here some opinions ....I am talking myself out of the job!
