Which one do you guys think are the better casting and will make the most power.

Oh yeah the AFR 220 100% cnc'd comp version vs. the AP220 S.

 

All Pro makes some nice heads.

Ask Yelvi or Feustal they should point you in the right direction

 

There IS no comparison. Just money. A set of All Pro's for a max effort 383 unconverted for reverse flow cooling are $5000.00+.

 

I dont know if they are THAT much old guy.

 

...they are close..i know a friend with them..and hes pretty close to that.

 

That is what they quoted me for a set sprung up and ported and ready to go.
That's the reason for the Toplines.That's unconverted MAX effort-- they sure flow good.

 

how good?

They just quoted me $2200 rtg minus the valve train.

 

That's for bare castings cleaned up. No port or combustion chamber work,no valves,no springs,no retainers no valve job and not sure what castings they have more than one.
When ya get them ya will need to take them somewhere and have all or part of this done.

Difinitely not a max effort sprung up and ready to go.
