That would be the flat tappet cam in that engine.
flat
You do not want to change from a roller camshaft to a hydraulic flat tappet cam! that would be adding friction to you engine(bad plan). you can go from a flat tappet to a roller cam but no one offers a kit to erase technology, or subtract horsepower.
If it has center hold-downs on the rocker covers, it's probably a roller cam.
A Chevy 305 with a roller cam will have MORE power than a 305 with a flat tappet cam if both are installed in the same engine. The horsepower of any 305 depends on what all is done to the engine. Changing from flat tappet to roller will gain some. There are other ways to increase horsepower and there are other ways to increase torque.
NOPE, FLAT TAPPET
They should be interchangeable as long as they are both flat tappet engines (not roller).

More information is required to answer this question properly. The best way is to pull the casting # off of the block. Is it a truck 350? car? year? roller? flat tappet?
Yes, just make sure you get the correct length pushrods.
No to the roller lifters in the 2.8 Ford V6. The 2.8 as well as the 2.9 has regular flat tappet lifters and regular rocker arms.
clockwise 15426378 The rotor turns counterclockwise and the order depends on if you have an engine with a roller cam or a flat tappet cam. If it is a flat tappet cam, it is 1-5-4-2-6-3-7-8. If you have a roller cam, it is 1-3-7-2-6-5-4-8. You will either have an H.O. motor or not. H.O. is roller motor.
The 1990 will take flat hydraulic.
