INLET VALVE,BLACK KWPM
An inlet valve, black-coated finish, catalog number 70-4603B (also listed as 70-4228).
This is an inlet valve listed in our records under the black-coated designation, catalog number 70-4603B, also cross-referenced to the older 70-4228 part number. Ed's shop record on this one is thin — it's a straightforward parts-book entry without a lot of extra detail attached.

An inlet valve is the poppet valve that opens to let the air/fuel charge into the cylinder and seals the intake port shut on the compression and power strokes. Beyond that, we don't have the specific fitment nailed down from what's in front of us.
If you're matching this against a valve already in your head or working from a parts book listing, give the shop a call and we'll confirm it's the right one before you order.
