Checking for bent valve sohc V6

[booblinker]

I have the head off and can see small marks on the pistons, but no marks on the valves. I have the head flipped upside down, is pouring water into the valve port and it not leaking down mean the valves are good? Or should I just replace them.
This is where I tried pouring brakleen and it didn't leak down either valve.

That was a copy and paste of my post from another forum.
-Water leaked out intake valves
-Put new intake valve in one cylinder
-It still leaks almost as much as with the old part

Should I have used valve lapping compound? Should I replace the head? This is a cheap cheap cheap build. Paid $100 for the truck, and want to have well under a grand into it. Plans it it are drive it to work once a week(I don't like to let running vehicle sit) and use it when I need a bed, or if my Chevy breaks down. Its am 01 4.0 SOHC 4x4 Ranger

Lap the valve and fluid check again.
