Product Description

BBC Stainless Steel Valves, for aftermarket heads

Stainless Steel Valves, 1.880" Exhaust Valves, 11/32" Stem +.150" Length

Used in many aftermarket aluminum cylinder heads


Here we have a brand new set of eight 11/32" stem, plus length stainless steel exhaust valves for BB Chevy.

These are +.150" long which are mostly used in aftermarket aluminum heads with 11/32" guides.

Aftermarket cylinder heads commonly have a raised spring seat design, which is done to improve port flow. Head manufacturers raise the spring seat surface up higher to allow for an improved port profile in the port below the spring seat area- as a result, longer valves are required.

Manufactured from Premium 21-4N material.

The straight stem design increases strength and durability over undercut exhaust valves.

Acquired from Precision Engine Parts who has been in business since the seventies and who are still going strong today.

A good choice for high performance street/strip engines running various cam profiles.

Valves have a tulip profile which are known to improve flow rates at high lifts.

Purchase is for a set of eight exh valves.
