Old Dog67

I have the valve covers that came on the burned engine and they don’t have a hump on them. Also the dynatard solenoids go directly on the rocker shaft (1 per shaft). My rocker shafts have a plug in them where the solenoids go.

I bought a 97 ch with a mechanical e7 350. The truck had factory Dynatard but the engine was replaced due to severe over heating. The replacement engine was not equipped with Dynatard but the truck came with the old engine. My question is will I have to change the entire rocker assembly or can I remove plugs and screw in Dynatard solenoids? Yes I will run the overhead while in there. I’m very aquatinted with Jake’s but never fooled with Dynatard.
