Just a few quick pics to see how lobes look after 4400 miles.
Lifters have less than a thousand miles due to originals collapsing.
Melling SPC-7 and Johnson lifters that are quiet at 1/2 turn preload.
Had to remove intake to repaint and reseal, so I wanted to inspect
while opportunity presented.
Does the lobe wear pattern on nose of lobe appear normal. Ran
a day ago to see if all pushrods were spinning ,and a few were slower than
rest at idle but then would speed up some at higher rpm. The lifter pic is of
one of the ones that were slower and still has raised center and good swirl.
If I try to spin pushrods when they are on base of lobe the lifter spins on some
and just the plunger inside the lifter on others. Always used either Brad Penn
or rotella with ZDDP and filter was clean.

Thanks for your thoughts
