302 heads-Is it worth putting them on a stock 318

Dont have a flow bench. But on a 318 you dont want to hog them out or you decrease port velocity and hurt performance. Just transition them from a big port intake so theres no ridge and the air flows smoothly. I am using a Weiand Stealth #8022 which is pretty much an Edelbrock LD340 copy.

I'm sure if you stick these on a 340 or 360, you could go with bigger valves in these and do some serious port, runner, and bowl work.
