So I got my new EFI block, head, intake and EFI coponents from an 87 and I got a wiring harness, ECU, and other goodies from an 85, and for the most part, I should be able to get em to work. However the 87 22RE block had broken timing chain guides so I went ahead and removed everything to install a new chain, guides, sprockets, etc. But now my question is, since I have the head off and the entire engine apart and strewn all over the garage... should I get anyhting done? Like should I have the head ported or should I consider a new camshaft? Also, since I took the head off is it mandatory to get it surfaced before I put it back on? Thanx in advance for any help..
