I’d be interested in seeing pics of what you have.

My old catalog shows them sold as bare heads only.

In the instruction sheet:
Quote
60917 is a NHRA Legal (Stock/Super Stock) version of 60919. All of these cylinder heads feature 210cc intake ports and 70cc exhaust ports.


As I mentioned previously....... get out the burette.
The max legal runner volume for them is 203/64.
