Would prefer to trade for a GSR head. The Prelude head is in great condition. Thrust bearings have probably come out of the bottom end though. (When the engine was pulled the engine was stalling when clutch was depressed and the owner had a really extreme clutch in the car.) Still need to pull the crank and check the block and throw a micrometer on the crank. Prefer Atlanta area sale or trade. Reasonable offers accepted.
