W5 Head Question

street demon said
If you can post some pics. Those are great heads and killer when ported right. Post some flow numbers if you are having them flowed. What valves are you going to run? Also what are your plans for the valvetrain? Are you going to be using a 48 block? Last one are those the newer heads with the blue plug on each end?

Yes, they should work out well on the new stroker. As soon as Shady Dell is finished with them, I will post some numbers. They only have two porting options at Shady Dell for the W5s (no Stage I, II & III). They offer a full CNC port for $850 (which I will copy & paste the description of the work done below) and a hand porting job for $1100 (which is usually for W5s that have all ready been cut).

We are in the midst of discussing valvetrain and which roller rocker setup to use. I was initially going to use the all of my parts from my W2 heads but have decided to go with new components and will be selling the W2s (including intake manifold and headers) off later. The W5s are 59 degree heads and I am going to start off with an OEM block (partially filled). Yes, these heads have the head plug kit in them.

Here's the CNC port info from Shady Dells:

FULL CNC PORTING: $850
Shady Dell Speed Shop has the worlds first and only CNC porting program for the MP W5 cylinder head. It features a true D shaped exhaust port, fully CNCd chambers that are opened up to 4.08 bore size, and a standard W5 intake gasket port window. See the W5 head section for photos of the CNC work. After the heads come off the CNC machine, they get the valve job performed, and then the seats are hand blended with a carbide and sand rolled away from the freshly cut seats. Depending on the intended application of the head, we also may widen the intake runner by hand at the head bolt bulge and hand blend/widen the intake short turn. Typically this mod is only done if the intended engine is over 400 CID or is an all out racing 340-390 motor. The final intake runners on the big version are in the 217 CC range with a 2.08 valve. Chambers are in the 68 CC range depending on valve seat depth (they varied wildly from MP).
