Speedmaster PCE283.1006 Valve Seat 4-Piece Set Ford 429 469 Intake +0.010

The Speedmaster PCE283.1006 is a 4-piece valve seat set designed for Ford 429 and 469 big-block engines, specifically sized for intake valve applications with a +0.010 oversize specification. This component is essential for engine rebuilds, restorations, and performance machine work where factory valve seats have become damaged, worn, or require replacement during a complete cylinder head overhaul.

Valve seats are critical sealing surfaces in the combustion chamber that allow the intake and exhaust valves to close properly and maintain compression integrity. The +0.010 oversize dimension indicates this set is machined to fit bores that have been enlarged by 0.010 inches, a common sizing option when original valve seats are beyond repair. As a Speedmaster product, these valve seats are manufactured to specification for reliable fitment and performance in classic muscle car engines and modern engine builds using 429 and 469 blocks.
