Introducing Modern Performance's CNC ported cylinder head and camshaft, MPx camgear combo!

We've made it super easy for you to get a CNC ported cylinder head, with Serdi competition valve job, oversize REV valves, BC valve springs and titanium retainers for your Neon SRT4. Now you can add your choice of Crower cams, along with MPx campgears to provide a complete top end package!

These heads are all checked to make sure they are all within clearance, decked .002 to make sure they are true and seal well. Then the heads are fully cleaned, and all threads checked. Next the heads are CNC fully robotic ported on a 5 angle CNC port on the intake, exhaust ports and chamber.

Instead of doing a 3 or 5 angle valve job, a SERDI valve job is performed, which gives us a much more uniform valve seat finish and better flow than a 3/5 angle valve job. In order to get more flow into and out of the valves, REV 1mm oversize intake valves are installed, and 2mm exhaust valves are installed.

New Manganese bronze guides, and OEM valve seals are also installed in addition to BC valve springs and retainers and new OEM locks.

Some quick notes:

  1. These are sold in a core exchange program. At checkout you will be billed $200 core fee that will be refunded once you return your good condition, not warped, complete with with cam caps. You should return the cylinder head to us within 45 days.
  2. Do you have a factory turbo, and limited modifications? Then this probably isn't for you. This CNC ported cylinder head is designed for extreme flow, perfect for a high horsepower Neon SRT-4.

    Could I get this in Crane valve springs and retainers? If not will this valve springs and retainers be able to work fine with Crane 16's?

      We cannot offer other valve springs and retainers as these come assembled from our machinist. You can use different valve springs with different cam manufacturers with no problems. Think about it, Crane/Crower use one valve spring for a huge range of cams. Therefore, the same range of cam from a different manufacturer can also be used.
