DOD Delete question

[SinisterGT]

Hey all
I’m about to do a DOD on my 08

Since the heads have to come off, Id like to get them milled to bump up the compression.

My question is for those that know for sure,
How much can the heads be milked safely for the most power gain.
I’ll be running the stock LS9 Head gaskets, unless I can bump it up using head gaskets alone, and if so which gasket would I use.

Also if milling the heads, what pushrod length would I need?

Thank you in advance

I’ll be using the Brian Stage II N/A camshaft if that helps

I would direct those questions to Brian tooley racing - they would tell you what compression would work best with that cam.

Also, they will spec pushrods for you. If not, get a comp pushrod length checker. Ls7 lifters are notoriously picky, you want as perfect of preload as you can get.
