318 head porting for the average joe

It's not about staying where your/I'm at, I don't know if you notice but most asking for build advice especially for 318 are generally novist and Super Stock, F.A.S.T, Pro Stock, Sprint Car, Nascar info and mods might be a little above their pay grade while they're trying to figure out which RV cam to run, most that know what their doing here basically document their builds here.
You are giving advice that contradicts the title of the thread.

No I haven't,
That figures. When you have and have seen results contrary to what people here say and repeat ad nauseum because they don't actually know. Its not hard to get a 318 head over 200 cfm and I have a set over 240 cfm that I ported myself. 200 cfm is plenty for an engine up to 400 HP.

Go put a ported 318 head on a 360 and see how that performs.....It may actually shock you.
