Valve guides....HELP....I'm in need of some size info!

[gettingreasy]

I need to find some shouldered valve guides, they will be going in a 74" 66 shovel but any valve guide maching this desription will work(or can be made to work). Okay the stem diameters are .308" for the intake, .338" for the exhaust. The OD needs to be .580", the length from the bottom of the shoulder needs to be at least 1.90". Bronze or cast iron, I was wondering if anyone may know of automotive(or otherwise)with stem diameters of this size. And for anyone that cares the old ones were the copper ones that manley used to sell with their stainless valves in the 60's/70's, this engine was setup back in the day, had huge valves(which is wierd cause stock ones are PLENTY big)and it has B grind Andrews cam and a "Twin Throat" S&S carb. ANY help would be great, even what the stock sizes are(both guides and stems), thanks.

Hi jesse check with SI valves they have a large inventory of bronze valve guides. I checked their harley listings and all was correct except for the OD which leads me to believe these had been bored oversize at one time. But check with them anyway as they may have someting that will work for you. their number is 1-800-564-8258 and their website is www.sivalves.com (http://www.sivalves.com)
I also know of another company that makes bronze guides and has a large inventor as well. called Rhoe or Rohe I have some info on them if I can find it I will post it as well. Shawn

Ya thats probably what will go in there but damn they're expensive, $12.99. We just need some cheap guides just to get this bike on the road. Does anyone have what size the stock guides are(48-79 use the same)?
