uhh... how is your valvetrain geometry NOT off?
you corrected it with shorter pushrods (which also constitutes more than "slapping them back on"). you slim .30 off the heads and the intake ports will sit .30 higher than what they were. maybe not a huge deal, but still off. sounds like poor way of doing imo.
I wonder the cost difference between a set of KB pistons for a 6.0 and milling, head gaskets and new pushrods.
new pistons will be around $200 + balance.
i haven't priced pushrods, head gaskets and machine work lately.
another question: I know the piston at TDC is above the deck on the block. how much further can it go before contact?

It is off man. But you fix that by using shorter pushrods. Dam. If you would look around this site, you will see that ALOT of people mill heads and .030 is a safe mill. It is not wrong and I am not the only one who has dont it! I dont understand your view, and Im sorry I dont. So are you telling me. That every person that has heads milled on an LS1.. Their engine is gonna blow up?

you didn't mention anything about correcting it, so i mentioned that. Still confused?
milling heads isn't something new, i've had 2 engines with the heads milled.

Scroll back up to my post 10. Read where it says I used shorter rods...

Deals like this is EXACTLLY why Comp makes a pushrod length checker.
Also.... What is .30?

the intake ports;
there are two ends. one on the INTAKE and one on the HEADS.

Ports on the heads will not sit higher if you mill them, im sorry.
