Had these for a while but never ran them. Casting #3946074 They came on 1969 Corvette L88 and ZL1 427 "Hi Perf", 1969 YENKO Camaro 427, and 1971 Corvette 454 ci. 425 HP LS6 "HI PERF" They are rectangular ports and the ports have not been touched at all which is hard to find. They have not been resurfaced either, the original cylinder number castings are still perfectly printed on the qhench area of the combustion chamber 1357,2468. They havn't been polished or painted at all, the Winters logos are both still on each head and havn't been ground off or polished. Guides and seats should not need to be replaced but need to be touched up. NO SPRINGS OR VALVES. All spark plug threads are good. No corrosion around the water jackets at the intake. Asking only $2500 because they are w/o springs and valves but I have Manley valves to fit these for sale separately if needed. You will find these going for $4000 on Ebay. Good Investment. Open to trades. Call Zach (408)533-2042 azacharya@gmail.com
