660 bronze is actually a bit tough and may work just fine.
The only thing that may come into play: Bronze bushings are meant to be squished when assembled. Then, you ream them to the I.D. spec for the cam.
So, the O.D. may have to be fiddled with to get the right specs you want.
That is most likely why they use a needle bearing, as once a bronze bushing is installed and "squished" You'll need a special reamer to get in there and open it up to the right size.
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country

Oh, ok interesting. I'll have to ask the machinist about that. I would like @ 0.002" clearance, as spec is 0.003". Don't want to go too tight.
I am only doing this on the left (large) cam journal. Would you recommend using a solid round bushing, or half circle bearings? (Like rod bearing)
I know you seem have a lot of experience in machining so I would be interested to hear how you would address this issue.

Actually, what I meant is do not heat the screw. If you do any heating, stick the head in the oven at 300 degrees for maybe 10 minutes. If you have an infra red gun you can slide the oven tray out with the head on it and check the temp before removing it from the oven.

Got the stuff to install a bearing into the pulse generator cover. NSK 6802 ball bearing. 15x24x5 size. Bronze bushing stock will (hopefully) be turned into a spacer to fit bearing into cover bore. Bore is 25mm so a small spacer is needed.
Cleaning up the head, and I have the bronze stock for those bushings. Will drop that off when it's cleaned.

Did you get the screw out?

Yes, it was just tight enough to make the screwdriver slip, but not seized thankfully. The oil pump screws on the other hand were totally seized. I totally stripped them. Cheap set of left hand drill bits and I had them out in no time. I won't used anything else to drill threaded stuff out anymore.
