QualCast 10-1195+15

QualCast 10-1195+15 is a single intake valve with an oversize stem for selected Chevrolet Small Block engines. The +15 version has an approximately 0.3569" stem and requires a cylinder-head guide machined for this oversize.

Application / fitment

The 10-1195 family is used as an intake valve in selected Chevrolet Small Block engines including 350 CID applications. The +15 version is not a standard-size direct replacement and must be matched to the measured guide diameter by a cylinder-head machine shop.

• part type: intake valve
• position: intake side of the cylinder head
• selected applications: Chevrolet Small Block 350 and related heads with matching dimensions
• version: +0.015" oversize stem
• application condition: professional measurement of guide, seat and valve installed height

Installation requires guide reaming or honing to the specified clearance, a 45° valve-seat service and verification of keeper-groove position. Never force the oversize stem into a standard guide without the required machining.
