Looking for a good pair of 1972 #3998993 Chevy S.B. heads with a cast date of A-72 - January 1972. Have to be the exact cast dates and year i am looking for. I might be looking at trading a pair of my 487X heads, year- 1971-with cast dates Dec-23 for your 993 heads if it's possible. 487X heads are totally stock. The heads were recently redone with new guides, seals, and factory valve grind with original valve springs and hardware. Send me a message if you have what i am looking for or know someone who does. Thank you.
