NEW LS3 Splayed Valve Heads - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

FTI-EDC · 10-30-2011, 10:17 AM

Just got notice of the release of a serious player in the LS3 cylinder head market. Putting unlimited racing technology into the street scene. Not for the weak of heart!

Mast Motorsports, the leader in Gen IV LS hand built crate engines and performance products, is extremely excited to release our most engineered aftermarket LS cylinder head to date: The LS3 CNC Splayed Valve Cylinder Heads (P/N 510-205).

The splayed valve head uses completely redesigned valve locations. This technology produces greater flow numbers at lower valve lift with less port volume than our highly successful 11 degree LS3 Black Label medium bore heads. This combined with the improved air/fuel mixture tumble characteristics of the splayed valve positions results in our most efficient cylinder head design to date.

The splayed valve cylinder heads are designed for any new Gen IV LS engine with 4.000” or larger bore. This cylinder head accepts Gen IV LS3 rocker arms and intake manifolds without modification. It utilizes a 2.165” intake and 1.650” exhaust valve and 68cc combustion chamber standard.

With new valve location will this force us to cut down on cam size? I mean... Let's say I had the G6X3 or TSP VVT 3 already installed, would it have to be remove for piston to valve clearance?

I would've loved to try these out with my new combo! Maybe some day I'll swap to them.

I'm sure there is more valve drop engineered into these heads so you can run more aggressive cams.I need a better job.
