No on PTv clearance check. My mistake was getting pistons that are true flat tops with a 625 lift cam and .030 milled heads and 3 layer head gaskets.
this time around they are 7 layer gaskets, stock unmilled heads, and a 575 lift cam.
the pistons in the 5.4 are what bit me in the butt.
oh well, he gets a bigger engine and it will have more torque for his Jeep.

What is the mark in the cylinder?

not out of the block at all.
3 layer replacement mls head gaskets
he didn’t want to buy forged pistons
the “mark” in the cylinder in the earlier picture is just assembly lube that was puddled at the ring gap and I rotated the crank and it just sat on the cylinder wall.
yes, I know it was a duration issue. As I explained earlier, its all been resolved.
the Howard’s rattler cam will go into another 5.3 that is going to get bored and stroked to a 383LS with forger rotating assembly. That project is a ways down the road and money is real tight so it’s not a priority anytime soon.
