Head Questiuon

Mortec says this "14102193...87-up...305/350......1.94"/1.5" valves
"

I thought the valves where like 1.94/1.6. Nothing states what the other specs are, combustion chamber, intake runners and such. Any hlep would be appreciated. Thanks.

They're 350 TBI truck/Caprice swirl-ports.

Dung.

None of the other "specs" really matter too much.

If you're building a motor where the valve diameter matters, then those are the wrong heads.

A search of that part number, or just "193" and "swirl" as keywords, in a search on TGO would reveal a lot more than valve diameters and insightful dung replies.

The heads are indeed from a TBI truck/Bcar and they are useful on a mild performance street engine, especially a budget-minded build that retains good fuel economy.
