	(Mortec numbers site says they were also for "69 Z's) I have a set of 1970, 370 HP, LT-1 heads casting # 3947041-X These heads were both cast on March 3rd, 1969. Heads are 64 cc chambers, 165cc intake runners and 65cc exhaust. They have 3/8 screw-in studs and 5/16 guide plates. 2.02 intake valves and 1.6 exhaust valves. Heads are unmolested, never ported or polished, and appear to have never been surfaced. They have new valve guides, umbrella seals, Z-28 500 lift valve springs, and a 3 angle valve job. These are fresh and ready to bolt on. E-mail me for pics. [email protected] $500.00 plus freight, deliver lower 48 only, or may pick up http://www.mortec.com/castnum.htm  |
