My son and I pulled one of the heads to day and found cylinders at 3,65. I guess that is first over size? 3,62 +0,03?
The good thing is it still has the cross hatch pattern and no edges!!!
The lifter gallery also had the mod to increase the lubrication of cam and lifters.

So, so far its looking good!

 

Those 272's have a lot of meat on them. I have seen them .125" over

Mine is at .060' with no problems.

Glad yours looks good still and has the lifter Mod. I have not done the mod yet but I can see where it would help.
