These Valve Seat Inserts are specially sized for Harley-Davidson Shovel Head 1200 and 1340. They are designed to effectively dissipate heat for consistent valve sealing. Each seat insert has a radiused edge for easy installation and they will harden during engine break-in. Both sizes are .400" Thick.
AV&V Valve Seat Inserts are being discontinued by Goodson, so are subject to stock on hand. They are being replaced with Kibblewhite Valve Seat Inserts.
