This budget friendly head  is perfect for your 509 to 540 Cubic Inch operating below 6500 RPM. They come fully assembled with the identical components found in our higher end CNC ported cylinder heads; such as ARP rockers studs, PAC Racing springs, viton valve seals, AFR adjustable guide plates, machined bead valve locks (not stamped), hardened spring seats and our one piece 8mm 21 4N Stainless Steel valves. They are available without any parts for the DIY. Sold as a single piece, 2 are required per engine.
