This is it, the big boy heads for those 572's!

A 2.225" intake valve flowing 376 CFM, while retaining 100% compatibility with factory offset rocker arms that use factory oiling, ANY Max Wedge intakes, factory valve angles and factory exhaust flange! What does this mean? It means your rocker arms, intake manifold, pistons and headers aren't going to add thousands of dollars each to your overall build, as they would when you go with other older cylinder head designs that require custom pieces for all those areas. Or, if you have some of those parts lying around, or you are able to re-use from your current setup, then even better! 

These also include other trick pieces already installed, like Titanium retainers, etc. They do require 3/4" extended reach spark plugs (use our part #138-1000) and special longer head bolts, see our special special Trick Flow head bolt kits also listed.

This version is supplied with valve springs which will fit most HYDRAULIC ROLLER cams and are specified for up to .700" lift. They also feature Trick Flow's heart shaped 78CC combustion chamber with angled spark plugs. Trick Flow part number: TFS-6161T784-C02. These are sold individually (one head per part number,) so order quantity of 2 if you need a pair of heads.

Our Billet Aluminum CNC valley plates are manufactured from a solid piece of 6061 Aircraft aluminum. They feature a removeable access plate in the middle with a re-usable O-ring seal. This part number fits "RB" (413/426Wedge/440) engines only.

These work best with raised port heads such as Trick Flow 270's or Indy's. They can also be used on non raised port heads, such as Stealths, Edelbrock Performer RPM's, TrickFlow 240's, etc..., but we recommend using the "Batwing" gasket holders to cover the gap which will be present between the plate and the bottom of the cylinder head.

We also offer a Lexan clear access plate (part number 200-1217), so you can see what is going on with your valvetrain down in the lifter valley (even while the engine is running!) A super trick setup you won't find anywhere else.

Please note: Aluminum is very soft! Even sliding it across a table will cause very small scratches. We try to be as careful as possible during manufacture, but occasionally there will be some surface scratches on these resulting from normal handling during the manufacturing process. It doesn't affect function at all, and the vast majority of our customers would never give any of this a second thought, but we have had some people who are VERY particular, so we thought it would be worth mentioning beforehand.
