Small block 340 with X-heads. My machine shop is having a problem finding replacement valve guides in an over-size to press into the head. The heads had bronze guides and some of them were moving due to previous incorrect machine work. I am looking for a guide that I can have pressed into the heads in an over-size. Does this part exist? If so where to find it? Any other solutions? My machine shop is not Mopar-centric...

I am looking for an valve guide in 0.372 inside diameter to machine for a 0.375 valve stem, the outside diameter needs to be slightly over the stock .500 size. Machine shop says .503 to .505?

I've seen .530 OD guides. But you also need the reamer.
I can say in almost 35 years I've never seen your issue.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

A couple of years ago I needed some .507 od guides and found them through PEP Precision Engine Parts. Go to their site, click on " downloads " then download the PEP catalog by size. They list .372 id x .504 and .507 od guides. I'm pretty sure PEP can make whatever you need.
