BBC 360cc 24 Degree


360cc Big Block Chevy 24 Degree

Our big brother to the 345cc head, the 360cc Rectangle Port BBC head is hands-down the highest flowing standard port configuration BBC head for the money. The 360cc head features full CNC porting, EV-8 stainless steel 2.300" intake / 1.900" exhaust valves with 11/32" stems, magnesium-bronze guides, super-clean chrom-silicon dual valve springs, premium chromoly retainers and locks, and a race-radius valve job. Matching all of it with huge flowing CNC ported runners make our 360cc an incredible value. Compatible with most open-chamber, off-the-shelf pistons and standard stud-style rockers.
