I have been trying to get hold of oversize inlet valves without much success...

Anyone know of a source of inlet valves with 38.1mm head diameter and the 9/32 inch stems? The only ones I have found so far have 6mm stems.

Going by GR's recent comments the 6mm stems may not be the best choice, as the heads of the inlets are almost kissing the exhausts.

Hi,

I have some Paul Ivey 37.7mm 9/32" u/c stems.

Thanks for the update, I spoke with Paul Ivey a few weeks back and he reckoned he last made/sold some of these large valves about 15 years ago...

Are they marked up with the REC111 part number on end of the valve stem?

Had them for a few years.

Part No. REC - 118
