Putting head on slant six

Yup. Somebody somewhere in the past bent a couple or motor has been apart before and a couple were lost or whatever.
Look all to be same length but..... I think I'd get a matched set.
( and yes. I am a cheap s.o.b. so....)

They are the same length and I’m trying to get this slant six back on the road for as cheap as possible to save money for a v8 swap this summer. So I think I’m going to give em a shot as is.
