doubt you need a new motor, just a new head. 
the valve guides blow ass on our head. do a leakdown and see where the problem lies. then rip the head off and send to head shop. youll most likely need all new guides, and valve job. pretty normal im finding out. i have two with crazy compression numbers here in town. one apart in my shop now. whatd we find, exh valves that werent seating, and all trashed guides with one broken. I have a bad ASS cylinder head shop that i use here in vegas. they have done many world record honda heads. so if you dont have anyone, and dont mind mailing the head, let me know and ill have them do the head for you. maybe even port and polish while you have it off.

Dang nice numbers i did a compression test on my recently and got 175,160,155,60 
I pulled the head and rebuilt it the guy from the machine shop said i had loose valve guides im not sure if this was the cause for low compression but when the head is back on ill do a leak down to see if its the bottom end.
