Now that the 1.70/1.44 have dried up, what's the next off the shelf valve to make work.
Ford valves.....or 1.72 sbc/jeep
Stock length is 4.78
You could grind some off the stems, if you needed to. Hmm
Which would you want, less than stock by .111 or over by .150+
In '89, I used BBM 1.74" exhaust valves on the intakes, and 1.41" AMC exhaust valves which were a bit long & needed the springs shimmed. There is another thread here about a build using Ford 2300 valves from the later models w/7mm stems etc.
