A pair of MsPro Street cylinder heads in the Hi Flow 240cc version.
These heads come empty without internals, but we can of course assemble everything else to match your camshaft.
Version with angled spark plugs.
Suitable for Big Block Mopar 361cui, 383cui, 400cui, 413cui, 426wedge & 440cui
The optimized Hi Flow heads are just the thing if you have at least 440cui displacement and want to improve your performance with the significantly improved breathing characteristics of modern heads.
The advantage of the modern design is that this is achieved without converting to slower flowing Max Wedge ports.
As with the Indy EZ heads, longer valves were used to increase the volume above the valves. In addition, the intake and exhaust ports were further optimized according to modern knowledge. Right out of the box, they already have ports that are otherwise only found on fully ported heads.
- All original attachments fit
- With hardened valve seats, unleaded gasoline can be used without any additional additives
- The spark plugs are slightly angled. This results in better combustion, but can cause fitting problems with some exhaust manifolds or cast manifolds. (TTI exhaust manifolds fit!) If in doubt, send pictures!
- Use part no. ARP-145-3607 for cap screws
- We recommend part no. E-71 or E-298 for spark plugs
- The valves are larger and longer than on the original heads. The area above the valve seat is also significantly larger than the original.
-The rocker stands and valves are higher than on original heads; longer pushrods are necessary in any case.
-Very high quality workmanship and finish.
-Finished with attention to detail.
-Extra thick in the area of the head gasket.
-Very smooth casting surfaces, indicating a very dense, less porous casting.
- All holes deburred.
- All threads deburred.
- 100% flat sealing surface for easy sealing of the valve cover gaskets.
- All threads for the exhaust manifolds are blind holes, so no more sealing of the manifold bolts to the water channel is necessary.
- 10 kg weight savings per side, resulting in 20 kg less weight on the front axle
- Blocked heat crossover, resulting in cooler intake temperatures and thus more power
- Much better quality than comparable heads from Edelbrock, Trick Flow, etc., with the same power gain
With these modifications and a few other optimizations, you can expect around 100 hp more power, depending on the project. For greater power requirements, we recommend INDY cylinder heads.
