Im trying to get the most power out of my ls2 so i plan on ordering a FAST intake ported T-Body and i wanna get AFR 205 heads but was wondering if i should leave them unported or not. What are the pros and cons on porting AFR heads? Thanks

Sinister, here is what Tony Mamo sent me when I broached the subject with him. He opens the chambers to fit a 4" bore and minor porting. It picks up about 2cc in the chamber so milling is recommeded unless the new compression ratio fits in your plans.

intake .100 .200 .300 .400 .500 .550 .600
stock na 140 200 251 281 292 298
ported 72 150 221 268 293 301 304

exhaust
stock na 112 170 203 221 --- 230
ported 59 122 185 224 241 --- 248

I got a set of 210 Eliminators and I won't be porting or polishing them. There fine from the factory. Jeremy Formato said they looked great and wouldnt want to port them. Just my $.02
