TURBO LS PORTED HEAD TEST. HOW MUCH ARE PORTED HEADS WORTH ON AN LS3, 408 STROKER OR TURBO 4.8L?
Richard’s latest series is all about what a particular bolt on can be worth on your LS engine build. It started off with a video on oversize throttle bodies, then went to intake manifolds, and now we’re talking about cylinder heads. They are the lungs of an engine, while the brain is the camshaft. So what are a good set of ported cylinder heads worth when bolted onto an LS engine? And does it matter whether it is a junkyard or race combo?
Check out the video and find out what the real performance gain is.

WHAT’S IT WORTH? SHOULD I UPGRADE THE HEADS ON MY TURBO LS? HOW MUCH ARE PORTED HEADS WORTH ON A TURBO 4.8L LS? HOW MUCH ARE PORTED HEADS WORTH ON A STOCK OR CAMMED LS3? HOW MUCH ARE PORTED AFR HEADS WORTH ON A 408 STROKER? HOW MUCH ARE CNC PORTED GMPP LS3 HEADS WORTH ON A 468 STROKER LS3? CHECK OUT THIS VIDEO WHERE I DEMONSTRATED WHAT A CYLINDER HEAD UPGRADE IS WORTH ON SEVERAL DIFFERENT LS ENGINE COMBINATIONS, INCLUDING A 600+ HP CATHEDRAL-PORT, 408 STROKER. I ALSO TESTED THE GAINS OFFERED BY REPLACING THE STOCK 706 HEADS ON A TURBO 4.8L WITH TFS 205 HEADS. THE FINAL TEST WAS TO SHOW THE EFFECT OF CNC PORTED GMPP LS3 HEADS ON A STOCK LS3, THEN WHAT POWER THE CAM ADDS. I DUPLICATED THE STOCK HEADS VS CNC GMPP HEADS ON A LARGER, MORE POWERFUL 468 STROKER.
