Since my car blew the headgasket I went resurface the head.
The machine shop guy told me this is the last time that the head can be resurface.
After I installed the head, time it and everything the car begin the knock.
It knocks when it begin to boost and in boosting.
Went to the dyno shop, the tuners begin to dyno it and it knocks like crazy, he put the timming light the timming was a little advanced.
To stop the car of knocking he had to put the timming at 0, still I can hear the knocking, but it's hard to noticed.
So what do guys think it's the problem, the head?Or must uze a thicker headg?
Btw these are the specs of my engine.4g64 engine .20 over,microtech stand alone system,4g63 dohc head and comectic headg,0.51 mills.
Thanks
