I have a stock 302 shortblock and eventually plan on a 363-418" engine. I really only want to buy one set of heads and was wondering if 225 high ports could be made to work with a 302 with a custom cam. Car will be carbed with a stick. It will be street driven with weekly trips to the street legal drags on Friday nights. I've also looked at the 205 11r's but is the exhaust port going to be a limiting factor when you upgrade to a bigger engine displacement?
I was wondering the same thing about the valves and piston reliefs. Hopefully with a custom cam they can take the duration and valve size into account. I could also enlarge the valve reliefs i needed to. But I would prefer not too.
I'm not gonna say it has not been done before.I did it with a set of 225 Canfields and the right cam and it worked out well but more than likely you need to set them to the side right now and find some cheap 165 or 170 heads until you build the big motor.

Would a victor carbureted manifold be a good match for 225 high port and 1 7/8" headers leading to 3 to 3 1/2" exhaust? What size carb would be needed with this combo? Thank you for all the replies. I will report the results. I'm planning about a year for the car to be completed.
Still talking for the stock 302 shortblock?!? If running the stock cam degreed per the above, just slap a used Vic Jr on with a 650 mech sec carb. You'll have to find a suitable spring/ retainer setup for the interim rig also.
