engine help

yes, i am in the middle of deciding weather or not to pull my engine. the problem is that my gsx last year blew the turbo. after that i rebuilt the head and put a new turbo on. it was doing fine for awhile till i got on it. after i couldn't start the next morning. so that night i did a compression test and thee of the for were fine. but the one bad one read zero. i didn't know why. after that i went and did a leak down test. i heard air coming from the intake and as well as exhaust. so i figured i messed up valves or didn't seat them right. so i got a new head coming from a friend. so my question is should i pull it and rebuild it? or what should i do if you were me?

So, did you rebuild the head because of the blown turbo? Metal pieces everywhere? If yes then the block should be done also.

What was the compression on the 3 good cylinders? Is it possible you did the leak down test wrong?

If it were me, for the second time in there, I would pull the engine and do bearings and rings. Then you know it's good for a long while.

that's what me and one of my friends were talking about. that if i blew the turbo there is medal peace everywhere in the block. i think the 3 good cylinders were like 125-135. and i did my test three times and got the same thing. and the next day had a friend do the compression test and he had the same thing as well. he also did the test 3 times.

And now that it is going to be the second time i dont know if i should. but i think i am going to make it done right
