competition products is out of 200 cc cast iron heads
i need 72 cc and straight plug
who else carries them?

Try Lane Automotive (aka Motorstate distributing) 800-772-5266. Haven't talked to them recently, but they used to stock a mess of them.

Tri State also used to carry quite a few, might give them a shot.

Racing Heads Service ( A Comp Cams Company) owns the PRO/Topline heads now.
Ask them.

Do you want them bare or assembled?
If assembled to what lift cam solid hyd roller?
