318: too much cylinder head?

did you read my post?

first of all I want to make it clear. yes, I do understand this motor would make peak horsepower up near 7000RPM. that's actually the point.

The $1000 rockers are probably 100% necessary for trying to get .683" lift on a fast-rate roller camshaft. I'm however talking about using a .550" lift solid grind.

I'm not a dyno owner/operator and hence would not want/need a one off adjustable belt driven camshaft system.

Stroke is the key? a 3.31 stroke is easy to overhead? Ede heads are too much out of the box? It's funny how this theory seem to only applies to 318 engines and never 340 engines.

and lastly I am not trying to replicate a 414cube 615hp engine build from a magazine article with my 318.

with the theory that it's better to over-port than over-cam an engine.
I'm asking. "what would these heads go like on a 318?"

I should probably also ask. "What would these heads go like on a 340?" (A whopping 5% bigger in displacement than my 318 )
