I have a set of small bore AFR 225 heads ported by Larry Meaux Racing that I have determined are a bit too "serious" of a head for the things I'll be doing with my Nova (cruising, car shows, not racing). They have been milled to 55cc chambers and have had 1000k miles since a full refreshing with upgraded springs, locks, retainers, valves, seats and seals according to the previous owner. They made 497rwhp/457rwtq on his 3.90" bore 383. Below are the flow numbers for the heads as given by the p/o, although the methodology is a bit suspect as the ports on the bench were not matched well to the head's.

Intake Lift/CFM
0.100 -- 26
0.200 -- 146
0.300 -- 203.5
0.400 -- 259.6
0.500 -- 306.3
0.600 -- 330.7
0.700 -- 333

Exhaust Lift/CFM
0.100 -- 66.3
0.200 -- 113.7
0.300 -- 156.4
0.400 -- 195.9
0.500 -- 216.4
0.600 -- 230
0.700 -- 337

Revised my price today.

 

Anybody know what the compression would be on a stock 02' fbody engine. Would fly cutting be needed with say a torquer 2 cam?

 

sent you a pm

i was just looking a little closer.it looks like those heads are part#1510 which are 205 heads.225 should be part #1610.

 

God thats tempting..... so tempting..... dont do it....

 

Only guess could be they are 205's ported to 225 size runners, but that would be pretty expensive to have the runners CC'd exactly.
