I was surprised to see the thread that mentioned lawsuit(s) over cylinder heads and thought about posing some comments perhaps as a point that some might have opinions about. The following are some of those thoughts:

Caveat: The comments here are not intended to cause problems but to perhaps help clarify some points, not ruffle feathers. I know what the rulebook states and I have seen and tested many heads that were passed as legal. That term is interesting to say the least.

Stock Eliminator Cylinder Head Preparation
Current rules both written and what is visually allowed in Stock Eliminator drag racing is somewhat nefarious relative to practical applications. Each year some nuance is brought forward that had been not allowable in previous years. In order to have a competitive cylinder head package for a given engine, careful preparation is required.

Cylinder Head Preparation Points and Comments
1) Clean and inspect cylinder head castings (Magnaflux for cracks)
2) Prep guides / bronze liners / hone to fit stem sizing
3) Measure ports for CC volume – record notes – casting number verification
4) Prep ports and flow test / Record for File
5) Cut valve seats / Face valves to match as required
6) Measure combustion chamber CC volume
7) Disguise port work with chemical etching / ABS Cheating Bastard Blaster / or equal
8) Flow test and verify final port volume requirement
9) Cut deck surface for final combustion chamber CC requirement
10) Install screw in studs if necessary
11) Mill head bolt pads compatible and perpendicular with cylinder head deck surface
12) Finish for seals / spring seats / cups
13) Cut intake manifold mounting surface appropriate for deck surface removal
14) Note for distributor spacers and gaskets if required
15) Mark with SN and Flow File Documentation
16) Hope for accurate feedback from Customer or engine builder

Does this follow with your experiences ? What say y'all?
