Yup, I always debur my engines and parts for that reason. The 920 heads I bowl ported last year and are on my Cudas 273 were surprisingly clean ports compared to the BB heads I've ported from the 60's and 70's. I just did a light clean up in the bowl, back cut the valves and gasket matched the intake side. My car has a 904 with 2.94 gears and my carb was way too rich and it gets just over 15 mpg with the 275-60-15 rear tires on it turning about 2500 at 65 mph. It's not fast and the mileage isn't great. I think I can get this 360 to get over 20 and have some power when needed. I'm hoping anyway.
