With my car pushing 150k miles on it, and it sounding like a TDI jetta at idle, i need to do something about it......

So i worry about my headgasket everyday i drive to and from school(40 miles round trip), So ive know i need to replace that, and me being me figures while im in there why not buy the $900 rebuild kit.. http://www.importperformanceparts.net/ ...havnt called them about that yet, but does anyone know if they have the 80mm bore pistons?? cause all they have listed is 81mm......and ill probably go with the 11:1 compression........and maybe throw a wet kit on it.....but we'll see

my question is: where can i find a rebuild kit for the Head? i know colt cams is working on the cams, but what bout valves, rocker arms, valve guides..ect???? anyone know a good place to find those??

I want to do this cause i got the SR waiting to get built.....but that is a $6k project, and to rebuild this little beast shouldnt be more than $1,500....and i need a reliable DD...........so any help would be great....thanks everyone.....

and if your just gonna say "get a new car" or "do a swap" dont bother posting, and cluttering up my thread...........i drive a QG cause i have NO money.....but the rebuild kit to me is the best way to go....
