I want to do a frank swap with k20a2 head and don't know the differences if any between the two blocks! Also does it matter if they are long block or short block?

 

a shortblock is just the bottom end, which is usually cheaper. a longblock is the entire engine (head & block). i would personally try to get a k24a2 instead of the a1.

Ok, now I see!! Eventually I want to go F/i, so would the a2 still be better or the a1?

Depends... will you lower the compression on the k24a2? If not, go with the a1

 

I heard the k24a2 costs alot more then the k24a1?...........

About a half hour of research will get you an answer to that.
