Ive tried doing some searches, on google and on here, for some possible engine swaps or performance upgrades to this wonderful FE engine

From what I've gathered, please correct me if Im wrong, the F2 engine is *basically* a stroked version of the FE. I read the Mazda engine interchangablitlilty, wow I can't spell, guide and its VERY brief on the F series engines.
Im also wondering if the head will be able to interchange from the two (3 valves per cyl. verus 2).
Is the FE engine a lost cause? Should I look into a BP swap?
Any links, information, or ANYTHING will help me out a heck of a lot!
Thanks in Advance, and sorry for posting in the wrong section!
