318 head porting for the average joe

Not everyone running 11's with a small port 308 is a pro engine builder. Quite the opposite. But by all means stay where you are.
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.
Have you ever ported a cylinder head let alone 318 heads?
No I haven't, I've mostly done the 340/360 top end on a 318 with 340 type cams in the past, right now I got the Mopar 380 hp crate engine.

Kind of my point when people/novist are looking to make more than a stock 318 head can provide and their more than likely not gonna port saying all these racers can do a lot more with similar size head ain't really helpful to most.
