Product Details

The Airflow Research 1450 Renegade Race cylinder heads represent a complete redesign of AFR's proven Small Block Ford cylinder head platform. These high-performance aluminum heads feature 205cc intake runners with 100% CNC-ported combustion chambers, intake ports, and exhaust ports, delivering exceptional airflow for serious street/strip and race applications.

Key Features:

  • A356 aluminum construction with 3/4-inch thick head deck for strength and durability
  • 58cc heart-shaped combustion chambers for optimal compression
  • 205cc intake runners and 70cc exhaust runners for maximum airflow
  • 2.080-inch intake valves and 1.600-inch exhaust valves (lightweight 8mm stems)
  • 100% CNC-ported combustion chambers, intake ports, and exhaust ports
  • Competition 5-angle valve job for improved flow characteristics
  • Bronze valve guides and ductile iron valve seats for unleaded fuel compatibility
  • Dual valve springs with damper, 210 lbs. seat pressure, 0.710-inch maximum lift
  • Exhaust ports raised 0.125-inch higher than stock
  • Stud mount rocker arm design with 7/16-inch rocker studs

These fully assembled cylinder heads are ideal for 331-392 cubic inch Small Block Ford engines operating between 3,500-8,000 RPM. The robust construction makes them perfect for heavy nitrous oxide or supercharger applications. Maximum intake flow potential reaches 331 CFM at 0.750-inch lift. Requires aftermarket pistons notched for valve clearance. Sold as a pair.

Good

easy to purchase.

Fast delivery!

Great service and cheap prices.

A Quick delivery great price

Quick and easy. Hopefully the item that arrives is as ordered!

Overall, I was pleased with the purchased despite a long waiting period for its arrival due to it coming directly from the manufacturer. Better communication around shipping ETA would have been preferred.

Great price!!! Saved hundreds off Wilwood brake kit! Thanks!!!!

Fast, and easy!

Best Price I could find, fast shipping. I shall return!

Lowest prices around the web and excellent customer service. The only real issue was the wait between placing the order and when it was shipped. Took 4 days but I chalk that up to the large amount of business they due to their prices being so competitive. For the lowest prices that I've seen I didn't mind waiting a bit longer!

Very fast shipping and product was secure in package to avoid damage....will be ordering from autoplicity again for sure. Also the price could not be beat.

Superb company! Autoplicity had the lowest price, shipped it quickly, and it was exactly as advertised - couldn't ask for better results!

Fast shipping. And great cust service.
