2.3n/a tweekers need help!!

Hey i'm in the process of porting and polishing another head.
It's non turbo but want to see what i can do with it and want some ideas.
Plus got a question about the valve guide bumps. How far should i go down with them? I been looking at some pics but hard to tell how much people have taken out!!!
I have a roller cam and a ranger header and the 5.o throttle body and have also gutted the upper and tapered off the lower and ported the lower runners with the intake on the head.
Is there anything else that i should get to complete this install it will probably take me another week or so to get this done i hope seeing how my tensioner broke for my timing belt and now believe that i bent some valves can't get her to turn over more then once.
luckily it did this sitting in my drive way..

Also wanted to know if the turbo computer will work on a n/a engine? and what year should i get it from??

One last question is there any benifits to switching to mass air???

Thanks apprecciate any help you can give me...

I was under the same imppression myself.
But shes acting like something is binding i can turn the crank by hand fine and the cam also ive tried over and over to play with the timing and when i turn her over it's like she aint got enough juice or something. Don't know what a bent rod sounds like sorry about the vague description.!!!!!
