Ranger Roller Cam Questions

I recently dropped my spare turbo coupe head off at the local machine shop. They've recut the valve seats, installed seals and brearings, and worked some off the roughness out of the intake side. I dropped off a ranger roller cam to go into it. And according the tech working on the head, he's concerned that the ranger valve length and width is different then the tbird. How have you guys gotten around this issue when installing the ranger cam.

Thanks!

When I put in my RR cam years ago, I just installed the cam, replaced the lash adjusters for the heck of it, and used the correct roller followers for our valve stem diameters. Worked perfectly first time out, and has been fine ever since, but I did install an adjustable cam pulley a while back and retarded the cam by 4 deg to give a little more high RPM power. I seem to remember the cam and followers I got was originally speced for a 91 or so Ranger. My memory might be foggy on the year of the cam / followers, as I did the swap 15+ years ago.
