what is acceptable when doing a leak test?
No leak at all?
a few drops?

 

none. Do a valve job and call it a day.

 

none. after a 3 angle valve job is done they wont leak at all?

 

nope

 

Have your machine shop check for valve wobble too. Poor valve seal can be caused by worn valve guides.

 

I could see valve wobble causing issues when the valve is open but with the valve closed under full tension from the valve spring it seems like to me it screams valve seat/valve wear

 

It happened to me with my new head. Had .003" side to side wobble. Hammered the valves out of round because they arent square in the seat.

 

ah, yea now I can see how valve wobble would cause the valve to hit the seat at a goofy angle making it wear funny

 

when the chamber is full of water there is no leak....
when I fill it with fuel it leaks......

 

The head is already off. You need to lap the valves at a bare minimum. You can get a lapping tool and compound for a DIY project at autozone. Its simple.

 

You want no leakage at all.

 

X2 exactly....

 

Water is thicker then fuel.

 

probably good enough. any blow by would probably be about the same that is getting passed the rings at 600hp

 

checked the valves with the proper vacuum tool. exhaust were mediocre and intake were bad. the intake were the ones that leaked a bit.
doing a vale and seat grind. it wont leak at all after thats done.
if it does ill post again.
