Street Legal Performer 454 Oval Cylinder Heads
These oval port heads will support over 540 HP with 9.5:1 compression with the right combination! Unique oval intake port shape produces flow similar to rectangular ports, but the smaller port size provides excellent seat-of-the-pant performance and crisp throttle response. Semi-open chamber design maximizes efficiency with streetable compression ratios. The smaller-than-stock 11/32'' valve stems provide excellent flow and lighter valve weight.
