Late 80's swirl port heads 302/714's

I agree on the big port being better....back in the in 90's my brother in law at the time help me biuld a 318 with late 60's pistons in a 73 block with an RV cam that came real close to a 340 cam. We put 360 915 heads with stock 188 intakes, and 80's cast iron four barrel intake.

All in a light 64 2 door Valiant with a wide ratio 4 speed with an 8 1/4 with 2.76 gears....man what fun. Now it has a 340 with Ryan ported E-brock with a 6 barrel intake. Close ratio 4 speed and 8 3/4 with 4.10's.

But....the older I get I dream of low dollar motors for mileage and also builds for 1 HP per cubes with cheapest stockish stuff as possible.

Back to topic here my curiosity would like to see what a 302/714 head would do with some 360 valves....but if you loose the swirl/velocity then I think your wasting the heads and run them with just gasket matched if that doesn't hurt them. Cause if you do port work and it doesn't make them any different that doing to any other 318 then....I think the 302/714 heads should just left alone and use the for a good little gas motors....

Not sure if any of that makes any sense at all....LOL
