flat top OEM pistons? I am rebuilding my daily driver 1500 HD with the LQ4 6.0l. Looking to up the compression a little. No need to go forged. I'm just looking for more low end torque for towing. I'll also be adding a mild cam 210/216, .556/.561", 114LSA 112 ICL
Has anyone ever seen a flat top OEM piston? I have only found forged at >$600.
If not, do you think it is wise to mill the 317 heads 6cc, from 72 to 66cc?

The diff is not all that much, you would prob get more from putting a thinner gasket or having the head decked Had there been a OEM style flat top, it would help but to spend the $$ on a semi custom forged doesnt make sense.

Since this is a budget, daily driver build and will never see FI, I don't see the need for forged pistons. I can get cast dished pistons for $250. All the forged and LS2 pistons I have seen are $600+. Plus, I think cast pistons will be quieter since they won't expand like forged and the shop can adhere to tighter tolerances.
Maybe I'm not looking in the right places. Are there any OEM LS2 pistons for $500 or less?

I tried looking for some standard bore, forged flat tops for my LQ4 but they only make them in a .030 size. Got those instead, now I gotta get the boring done...
Of course I could have also gotten some LS2 pistons, but I want reliability just in case I want to spray...

I don't mind forged as long as they are around $500 or less. Can you use stock rods with forged pistons?
