Ok short story! engine was working fine,went to drag strip and heard a pop at 6000rpm. was no making issue on the way back home, but next day engine was working funny and making backfire on one cylinder. smoke is gray and deposite on #4 plug and rad is getting low. so since preston doesn't compress, i think that it might be the reason for engine shaking and backfiring. all 4 cylinder have 124 compression. thanks for letting me know.

Sounds like you know what the problem most likely is. Either way, gotta yank the head off...

Lol!
Bubbles are a sure bet of a blown headgasket when it happens instantly like it did.

Gasket is really black in between each cylinders but not busted. found out that one of the hla was busted (could push it down 1.5 cm) could it be possible that i was loosing compression in between of each cylinders? (would that be a reason for 124 at each cylinder).engine as 63k

A picture would help but black between cylinders should indicate it was leaking to some degree even if it wasn't blow. I'd check deck flatness as there is a good chance it's down a few thousandths between the cylinders.
