Re: valve lapping leak test
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

Re: valve lapping leak test
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.

Re: valve lapping leak test
probably good enough. any blow by would probably be about the same that is getting passed the rings at 600hp

Re: valve lapping leak test
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.
