AFR CNC-Ported P/N 1630 with the following upgrades:
- Additional hand-porting ($750) performed personally by Tony Mamo with his meticulous attention to detail.
- Upgraded lightweight REV 2.08 intake and 1.60 exhaust valves ($400) for better harmonics & valvetrain stability across the full RPM range, including Tony's valvejob and backcutting. Valves save over 35g in valvetrain mass versus the standard 2.08/1.60 AFR valves.
- AFR-8019 upgraded dual valvesprings ($100), good for .650"+ lifts.
- Precisely milled, finished, and assembled by Tony Mamo.
- Chamber volumes are spot-on at 69.5 cc's, intake-runner volume is ~227cc's.
Heads currently still are "record-holders" from Tony Mamo's flow bench, flow #s are posted below. Barely used, less than 800 break-in miles, and these heads are ready for you to bolt-on. Will work on all LSx engines (including LS1 & LS6s), especially the bigger 4.00"+ bores.
These are not a 'run of the mill' head for just anyone - they are specifically for someone wanting to squeak out as much HP from a killer set of heads as possible, with absolutely no sacrifice in quality or workmanship. The standard CNC'ed AFR heads are great....these have been taken to the next level.
The heads are in stellar condition - again, less than 800 actual miles on these heads - they have absolutely no damage whatsoever. I have well over $3400 invested. Will sacrifice at $2450 shipped -- Ready to ship NOW. Heads will be shipped in their ORIGINAL AFR box (packed extremely well) and will be properly insured against any shipment damage.

Quoted flow #s for the AFR-225 heads on a 4.06 bore; the below exerpt is a direct quotation from Tony Mamo:
Intake
.200....166
.300....234 (new recorded high I think)
.400....282 (tied with or a record)
.500....320 (another record I believe)
.550....327
.600....330
Just a killer piece from the crack of the valve to any lift we care about
Exhaust (more records)
.200....139 (definitely a record!)
.300....200 (another record...you guessed it)
.400....229 (tied perhaps?....LOL)
.500....243
.600....252
Sick piece....
