Default 1970 LT1 #186 heads

1970 LT1 Heads. Removed from a running 1970 LT1 corvette. Owner was going to have rebuilt but decided to go with aftermarket heads and did not want to keep these. He had them magnafluxed and checked out. Looks like they never had any seat work or other done. Magnaflux called out two small cracks in seats marked and indicated in pics. Dates shown indicate early 1970. $200 OBO plus ride. Mark

Not sure. All i can confirm is that these heads came off a stock LT1 1970 Corvette. Neighbor owns the car and still has original block that came in the car that had these heads on it.

Was the L-46 350Hp 350 available in 1970? If so it could have used the heads without guideplates.

The L-46 was available in 1970 and using the hydraulic cam, came with pressed in studs. These heads came off an L-46 1970 Corvette.
