Hi.
I have two one piece finned rockers plates that come from Dunstall 810 big valves head.
These one pieces have only the four end plate screws and not the oilfeed banjo bolt in the center.
The oil from timing arrive to one hose (instead of the stock feed) and goes to the rockers not trough the stock head oil lines but trough the rocker spindles.
The question is if such one piece rockers plate works well or is better to come back to the stock one.
More, they need gasket or sealant to mount well?.
Thanks.

Hi All.
Please, an answer.
Thank you.

If I understand you correctly, that method must use rocker spindles that are modified to allow oil to pass all of the way through them. If you use standard ones, you will starve one side of the head of oil.

Other than that, I see no reason why it wouldn’t work fine.
 
no advantage using them, as they rquire a hose and clamp, also you will still have to use the inner plates to locate the rocker shafts.
I made a batch of the same ones but I fitted pins to locate the rocker shafts so you dont have to use the inner plates. These items are only for looks, just like the finned rocker covers
