That all sounds good. The heads not the restrictive part. If you don't already have adjustable rockers, that's probably reccomended.
If you had some odd-ball components (extra tall valve seals etc. or poorly designed arms), you might find some clearance issues. But I think most popular components would work well with the right springs at .571".
Disclaimer: I'm still a bit new to this and could get corrected :-) Although, I'm on the 4th version of valve-train for my FE project.

You might need to cut the valve guides shorter and/or machine for PC type valve stem seals. There may not be enough room between the bottom of the retainer and the top of the valve guide. Easy to fix but make sure to check.
