Block Complete Roller

355 SBC Brownfield aluminum heads....?

Long block Chevy 350 bored to a 355. Has a complete roller set up: Comp Cams Roller cam, roller lifters. Chevy High Performance 1.6 roller rockers. Pete Jackson noisy gear drive. Complete set of racing aluminum heads (Brownsfield) with Comp Cam springs, valves and retainers. These heads came off a 400 funny car and ran only a few times. Compression is 10:1.
Heads are port matched and polished along with a Victor Jr. single plane intake to match.
.....Do you guys think it's a good buy for $1800??? From what I know AFR purchased Brownfield back in the day, the Heads any good??. Thanks

With those heads your looking at 540hp/480tq on your motor according to my desktop Dyno simulation.

If you go for cheaper heads like Edelbrocks, you will be: 495hp/460tq.

I personally think you could spend that much and make another set of heads better and they would be new.

If these ones you are getting are aluminum, then you could have micro-fractures near the exhaust vavle seats that can cause issue later down the line come up suddenly. Those are very stressed heads and would be really worth $800pair as they sit.
