Description:
Set of 16 Viton valve stem seals for Small Block Chevy V8 engines. Viton (FKM) is the gold-standard valve stem seal material — handles much higher temperatures than nitrile, holds its shape over time, and resists hardening from oil contamination. The fix for a smoking engine when the cause is oil control past the valve guides.
Specifications:
- Material: Viton (FKM) — high temperature resistant
- Quantity: 16 (full V8 set — 8 intake, 8 exhaust)
- Application: Small Block Chevy 265, 283, 305, 307, 327, 350, 400
- Function: Controls oil flow past valve guides; reduces oil consumption and exhaust smoke
Install note: requires the heads to be off, or specialist tools (compressed air to hold valves up) for an in-chassis swap.
