.....Have another set 6090 d heads. I have looked in Teds' listings and other info and can not find either on lists. These heads look like possibly like industrial heads as it will not take 1.9 intakes with out hitting plugs. They are 1.7s and barley enough clearance for spark plugs.
ANY HELP WOULD BE APPRECIATED.
I’ll suggest looking at the other end of the end as the prefix to the ‘6090-D’ may be there. These could be ‘C1TE’ heads or other early Sixties small valve heads.
