This is a bronze valve guide for 8mm valves, with oil seal cut-out as originally fitted to Fiat 124 1438 DOHC.
Typically 15.09mm (+/- .01) x 43mm long.
Also useful in 1300 SOHC engines with 15mm valve guides, for superior wear and heat management. 3.5mm shorter than stock for SOHC fitment, providing better flow.
New and unused.
