Default Please help confirm I am on the right track (cams and plate) - 01 Dyna

I recently picked up a Dyna for a steal. I have other bikes, and this is just a 'rip around town' type of bike. Mileage is 51k, and I am sure that I will need to replace the cam chain tensioners if I end up keeping it. I stated searching FB marketplace / CL / etc. for an upgraded cam plate, and I happened upon a deal that included THREE (3) Screamin Eagle cam plates, a SE oil pump, and an S&S oil pump (though its missing the gerotor parts) - all for $150. Also picked up two (2) cranks and four (4) jugs from 120R motors that will be resold cheap or saved for a future build. Anyway -

I believe I have to get 'conversion cams' to run one of these plates in my 2001 FXD, as they all appear to be the 2007+ style plates. Is this correct? I am thinking either Andrews 21 or 26 conversion cams for the stock 88" motor with an upgraded exhaust and A/C. I understand that I will need to rejet and have someone dyno tune the bike after the cam install.

Would someone (or a few of you) lend an opinion as to whether these plates each appear usable? Pics below of Plates A, B, and C. Thanks in advance!!!

Plate 'A' has cams installed, but includes the secondary tensioner. (I won't be using these SE 260 cams - if anyone wants, them let me know). Pics below of Plate 'A':



Plate 'B' - missing all accessories:



Plate 'C' - again, no accessories, and definitely less cosmetically pleasing:

Plate c looks like something came apart in that cam chest. There's a service spec for the bushings...not sure what it is off the top of my head. But the other two, from what I can see look ok...I'd use them as long as there were no excessive grooves in the bushings.
I think you need a block off plate to use the screaming eagle cam plate...not 100 percent sure about that...

Thank you for the response. The grooves / scoring where the oil pump contacts the cam plate isn't an area of concern, though, correct? You are just talking about scoring / scratches on just the actual brass bushings themselves, correct?

Also, I know that a friends used block off plates when her went to a gear driven cam setup. However, I'll be using the traditional hydraulic tensioners with these plates. I am thinking specifically of using Plate A with a brand new SE oil pump (~$115 from Surdyke) in the 2001 Dyna FXD (51k miles) with Andrews 26 conversion cams. I think I might also use Plate B (again with a new SE oil pump) in a 2010 Dyna Stage 1 96" to change out the stock cams.

Those cam plates are HD PN 25282-11 and can be used with conversion cams as the OP plans. He will also need the associated parts to complete the install, i.e., sprockets, chains, spacers and tensioners. No block off plates are needed. There is an oil transfer passage in the later cam plates that needs to be blocked off if the later cam plates are installed on early '99 motors only.

It is hard to tell about the scuffing/scoring on the cam plate where the oil pump seals agains the plate. Early plates use an o-ring to seal that interface but not the late plates. If the scoring is deep enough, there could be a loss of pressure; OPs call.

Thanks! I did put together a parts list for the ancillary items needed. I did plan to buy the sprockets, but need the chains, spacers, and the outer ('primary'?) tensioner assemblies.
I'll take a better look at the the scoring / scuffs on the rear of each plate.
