I've seen this listing in the GMPP book forever, but there is no tech info at all. Anybody have the specs. for this one?
Thanks in advance,
Bill

Bill,
What kind of "specs" are you looking for?
it's basically a raw casting, no bolt holes, no guide holes, .. etc.

I am not Curtis or any cylinder head ghru but I think that those originally are for the standard 4.840 bore spacing. These guys though are doing strange things with DRCE I heads.
After being machined and modified by someone like Curtis or Darin or other Good Cylinder Head guys those things can make for unreal power potential.

Bill,
The DRCE 1 casting was the best of the bunch I think, ..
It was originally 4.84" bore space but the casting was made thick
enough it's now used to make 5" bore space heads.
Some Pro stock teams still use this casting over the DRCE 2, ..
of course most are trying to use a rather weak DRCE 3 casting now.
It's a raw casting, valve spacing, chamber size etc are up to the
cylinder head person building the head. CC of the as cast ports,
um, .. there really isn't any, .. it's left very small so the port designer
can move the port where ever he/she wants.
They need specific lifter locations and cam designed for them.
