If they are off just a little they will gouge you cam and the metal shavings will sieze the cam and probably screw up alot more like oil pump, crank/rod bearings, cylinder walls and other cam. Do it right and use the caps that came with the head. It doesn't matter what cam you put in (windsor or romeo or aftermarket) as long as you use the caps for that head.
Thanks man. I understand the issue now. I was worried about clearance on the top of the journal. But I see that the issue would be on the sides were the caps meet the journal.

So all I have to do is use the numbered Windsor journal caps I took off and there shouldn't be any problems. I measured both cams with my mic and everything is the same. But I want to use the matching Romeo cam to be safe.

Thanks for the help!

I have never seen numbers on cam caps that were there for placement.

actually quite a bit of heads are numbered from the factory like this... the ones that we take apart that arent we number... so its either factory, or the heads been to the machine shop before.

Windsor caps are usually numbered from the factory.

I am having the same exact problem, the plug blew out in my 01 gt on the driver side and it was on clyinder #6 and we had tried to fix it by using the MAC plug repair kit and it was shuttering under a load and it didn't fix this problem when we "tried" to repair it and now we went to just getting a new head so and yea like my luck ended up with a windsor head...but my question is, if we replace the head do you guys think it will fix the shuttering problem that it first had? I bought this car like this and the guy had lied to me and said it was only a coil and it wasn't we replaced those and even checked the fuel injectors nothing. Please help!

You can use caps from another head if you line bore them. The caps on my SVO's are webbed and one of them was broken (dumb *** dropped it). I had to replace the whole cap and have it line bored. As long has its a problem with the clearance being too small you can have it machined.
