LA 360 drop in roller lifters

Hola. Currently in process of doing having some port work done on my speedmaster heads. I have been running a hydraulic flat tappet up until now. Have decided to bite the bullet and run a roller cam. Just looking for some recommendations for the guys who have been here. Leaning towards the solid side of the house. The pic is just to give you something to look atView attachment 1715724892
My next set of rollers will be Crane Ultra pro lifters.
Remember one thing "you get what you pay for".
What are the cam spec's and springs are you going to use?
