Honestly, it looks like a roller-ready block with a non-roller camshaft and lifters installed. This thread on another forum has some more info. He may be able to drill and tap the bosses to install the retainer and be fine.
I'm getting conflicting info on the lifter bores going to need to measure the depth< as for the bosses are already tapped ready for the retainer.
That was my thoughts, but now I just want to be sure before I go out buying parts that won't fit. If you could take a measurement that would be great.
Provided that my block is roller ready, here are my thoughts so far.
1. used intake, tb, fuel rail (already have)
2. junkyard gt40p heads with headers
3. new ford b303 cam
4. new timing chain w/ gears
5. new pushrods
6. new trick flow lifters
7. new crane pedestal mount rocker arms
8. new msd distributor
9. new ford lifter retainer
10. new ford gasket kit
That is about all I've got figured out at this moment, comments are more than welcome on this.

If I did something like that I would definitely need new valve springs now, I'm really trying to hold off for a few. But who knows
If you are planning on running GT-40P heads, you'll need new valve springs anyway. The explorer springs are pretty weak since the cam was very mild
