i just bought a 91 civic 1.5l d15b2 pgmfi throttle body injection it broke t-belt and bent valves im going to pull head and send to machine shop to get repaired and new valve stem seals my question is im thinking of getting a 3 angle valve job done do you think its worth it or should i do any other headwork to pep up motor a little i not looking for a tire fryer just while its already apart why not any advice
a freind mentioned swapping in a 90s model si cam and would def help alot is this true and a good idea

 

did u try contacting the major autoparts stores? you could probably get a rebuilt head for about 300 or less after core, and it would have all new valve components plus its already machined and checked for compression?
