Please excuse the "noobiness" of this question, I just have no experience with it so hoping I can get a bit of education. Essentially, I'd like to install roller rockers in my lowly Ford Racing crate engine. I believe I have the M-6007-X302 (the one on the far left.....) crate engine in my CAV. It's a good enough engine for me, and 340/310 hp/tq is plenty of power for me and my driving skills...

This engine has the basic stamped steel non-roller rockers installed. I'd like to install a good set of roller rockers. A few questions come to mind immediately:
1. Do I need to stick with the same ratio? In other words, if she has 1.6s now, should I stick with 1.6s in a roller rocker?
2. If above is a "no" is there any real advantage to a 1.7? And does a 1.7 risk some interference?
3. Do I need roller rockers which are adjustable at the rod end so I can set the proper clearance? Or is this all done with adjustment on the pedestal "polylock"?
4. I am assuming I can get the right geometry somehow - either through adjusting the pedestal height or length of push rod.
5. Should I take out the push rods and inspect measure? Is this necessary any time new rockers go in? Are rods matched to rockers somehow, either in length or shape of the tip?
6. What is the proper clearance spec? Is it done like any MG/triumph/porsche with a cold clearance spec and a feeler gauge? Or do I adjust to zero lash, then give it one half turn as I've seen in youboob vids for hydraulic lifters?
7. Stainless or aluminum?
8. Shaft mount or pedestal?
9. Should I use stud girdles?
Thanks in advance for any help.
