Need help transferring 74 block parts into my new 89 block

Yes and I have lifters and a stock cam shaft which if I went with the hydraulic roller set up I’d probably change to something similar I had on my flat tappet set up
That's what I would do. You can get your factory cam reground. I wouldn't hesitate using the roller block and valve train.
I believe this is what you’re asking for

Not the right number. The casting number is cast in the head and not stamped. The 360 should end in 308.
