I agree.. Don't change your heads. the port plates work. Call MPG in colorado. 303 762-8196. I have flow bench numbers if you want them, with and without the plates. Most machine shops don't know squat about these old heads. Find ONE expert on them and don't listen to anyone else. The ports are not too big. The heads flow better than all the iron heads out there for Chevy and Ford. And better than most of the un ported aluminum. You not driving the thing around at 2000 RPM anyway are you??? So build the stock heads and keep it above 3500 when your driving it hard. You'll be glad you did.
