so i have alot of play in my intake and exhaust valves for cylinder #4 all the others are the same. i had a misfire in no.4 the valve seal was egged out and broken when i removed the springs.

so my questions is....can just one head be rebuilt? or just have those valves fixed? im on a budget and $300 is alot for just the heads considering i have a bare block to try and finish up.

somewhere in this cars life something exploded in the exhaust. when i got it the entire exhaust from the cats back was expanded and the muffler looked like someone left off a grenade. car also had three different injector styles. no.4 had one ive never seen before.
