GUIDE,500+.004 USA MADE
A .004-over valve guide, made in the USA, part number 70-6301/004A.
This is a valve guide listed at .004 over standard size, made in the USA. The part number puts it in the 70-6301 series with an alternate catalog form of 71-0229-4, so if your parts book shows that older number, it's the same physical piece.

Our records on this one are thin beyond the basic description, so we can't speak to which engine family or year range it's meant for from what we have on file. If you're matching this up to a rebuild, give us your engine specs and we'll confirm before you order.
Because it's oversized by .004, it's meant for a bore that's already been reamed out that far over standard, not a straight replacement for a stock guide.
Sorry if we got something wrong here. If you think this information isn't correct, .
