multiple shovelhead questions
I figured I'd ask for a couple answers at one time. Bike I'm working on is a 1976 FLH, Prior owners replaced parts with chrome pieces (nacelle, cam cover, outer primary and rocker boxes) over the years they are now pitted and flacking. I have found most of the parts I needed ,but have a question about the rocker boxes, part book lists 17550-80 and 17552-80, I can't seem to find them at the various sites, however I did see sets 17511-60, they were polished or natural , they state from 1966-84. Are they interchangeable, am I getting to antsy and just wait for that part number the parts book calls them a cover kit. Is that number `17550-80 refer to the whole assembly (rockers, shafts, nuts)? Next question concerning the cam cover, reading through the posts I believe the this question was addressed but just trying to understand. Cam cover is chrome and pitted, want to replace, I have another (natural), You can't take one off and put the other on, right. Smart thing to do would be replace the bushings, which gets into measuring end play, understand how to do it with the breather gear but only way I've seen to measure the cam is to remove the tappets (rear cylinder) and use a feeler gauge. Additionally they say the bushing have to be reamed, which requires expensive equipment or getting an inside casing to secure the cam cover to and then line ream it so its true to the inside bearing. Does that sign correct, any one have a shop in Jersey willing to do small job like this?

The 76 head has all the same length studs front and back of both boxes and takes a -66 cover set
- 60 was still a pan head might be a misprint — and the - 80 rockers are different and. And work with mods but you see the mod front head installed
the cam cover switch is not that simple as you might think - check the end plays of both the cam and the breather has to be done - we have a tool that leaves the lifter blocks in place with a dial gauge - bushing can happen we have a OEM block that acts as a tool the cam cover is reamed from the flywheel side of the engine into the cam cover like a camshaft would install
you can PM me for more info about this as i am also in north west jersey stanhope its not a big state but the traffic blows most of the time

Thanks John, I was hoping you would answer, as soon I figure out how to PM on this site will contact you. I'm familiar with your area, we ride up from the shore to Rt. 29 or 32 along the Delaware.
