Fishin'? Yep, always fishin'. For facts. Like I said, never seen them tests. Wondering WHEN that port gets too big on whatever engine. Guys warning 'bout too bigga ports all the time. How's them Edelbrock 60779 ports? Too big? Too small? Or just right for his 318? Why? How much head can he put on the 318? Anybody test them Eddy's agin the 302? Can anybody point him to a test that someone else has done?
I would also like to know when a post gets to big for a given displacement. However, common sense is a good guide in many applications. To that end, (Back to the prior statement/question) When is an Edelbrock head good for a 318? While still a broad question, it would have several questions to go with it before a actual build is to take place. Building a well rounded package is the key and missing info should be a known.
The engine should work well in car, not just dyno'd and with great numbers. What works well on a dyno may not work at all in car.
Chrysler did a dyno comparo between 302 heads ported and 360 heads. (IIRC, unported) and found the 302 head to make 55 HP more. This is by now, very old info. I'll try and find the article for the build parts.

I betcha StrokerScamp could build a 87 octane, 12:1 motor with no quench if'n he had a mind ta'. But I'm shore with him for this build. Don't know this builders level of expertise, but don't you think it sounds like 9:1 would be smarter for a person without more experience? The guys callin' for more compression sound like they have enough knowledge to choose their own heads and pistons. Keep it safe for this guy.
Endeavor to persevere Stroker.
Agreed, it is hard to help in a thread when a general question is posted without enough info. General question gets a general answer. Details to help the problem get a detailed and/or a better answer.
While a person could build a 12-1 engine to run on 87 octane, this maybe the worst way to go for this person and there intended purpose usage pf the car.
Stroker makes a good point and you as well, but, the OE thread starter needs to reply with the above questions answered for a great reply, opinion, answer to this all.
