*FITS ALL ENGINES WITH GX200 AND CLONE HEAD BOLT PATTERN*
Want to bolt more horsepower onto your small block clone engine? The Shredder head is a high performance sand casting with much better ports than a stock style die cast clone heads. The Shredder head flows up to 25% more air than OEM 212/224cc cylinder heads.
With our complete head you'll get a 28.5mm stainless steel intake valve, 24mm stainless steel exhaust valve, both have 5.5mm stems and both are longer than standard clone valves at 2.600", a compression boosting 18cc chamber, heavy-duty 1.2:1 ratio 0.095" thick stamped steel rocker arms, automotive style retainers with split keepers, and 26lb springs. We have test fitted dual valve springs up to 60lb rates with no fitment issues in the spring pocket. This is a killer upgrade for your engine, and if paired with a suitable cam and carburetor you'll see nice power gains.
If you are bolting one of these heads on to a non-hemi Predator 212 or other Rato engine you'll need our stepped head dowel pins to adapt the 11mm holes in the block to the 10mm holes in these heads.
