Anyway the problem is that the valve guides that were purchased for a USDM SR20DE dont work for the exhaust valves. There is about .030" slop. So my question to anyone who knows is what valve guides will work and/or will 240 valve guides work?

Any help on this would be VERY much appreciated.
Thanks in advance guys.
