WIW 340 exhaust heat riser kit

NOS kit not in original wrapper but all the parts.

What does the valve measure across in diameter?

The early 340 manifold kit is different than the later kit.

BIG price difference

This is an over $150 kit. Lot more, if 340. I bet some parts flippers are already PM’ing him

The repro is $150
