    Yes they do , still usable but need a lot more work in my opinion ....still a great little head when ported and bigger valves installed.

    Piston and Rod Assembly

    Hemi flat top piston and ARC billet rod.




    This is one way to remember how the piston goes on the new rod.
    Factory oil hole, rod bolt hole and force fed oil dipper all on one side and the triangle or arrow go on the same side. Simply pic up the piston and set it right down on the rod.




    Make sure both wrist pin clips are fully seated in the piston.

    Checking Ring Gap

    Weather your using new rings or just check out the gap on your old rings . Install one of the compression rings in the cylinder and use the piston to push it down equally and measure the gap .



    Installing the new rings. Everybody does it different , I like my ring gaps straight across from each other....but this is just what I do.

    After milling the head around .060 which took me from a 22cc head down to a 17cc head .
    BEFORE

    AFTER

    Was able to get some good measurements for the push rods... with a .010 used head gasket , so I ordered 5.440 long push rods from NR Racing . Also ordered a new Predator .010 head gasket from Russell to.

    I like the how-to format of your build. It will be a good resource to new OMB members. Keep up the good work!

    Have you measured where the top of the piston is in relation to the deck surface? I ask because I went with the +0.020" Arc rod for my Hemi Predator build and that resulted in the piston being 0.004" in the hole. A 0.027" MLS head gasket was chosen resulting in a 0.031" piston to cylinder head clearance. My understanding is that due to rod stretch/crankshaft flex, this clearance should be >0.020". Of course my understanding could be wrong.
