Milled heads, stock cam? L76 Hey guys, picking up my new daily driver next week and want to do some mods. I'm thinking of milling the stock LS3 heads and keeping the standard cam. I know it's not a common thing people do but I don't want to mess with cams yet on this car. My past two daily drivers have become drag cars and this time I won't let that happen. Anyway I'm curious how much I can mill them without raising the DCR too much to run on pump gas (if thats possible at all) I figured because a stock cam wouldn't bleed off much.
The current mods already are LT's, dual 3", OTR style intake, 3.9 gear ratio through an A4. I want to see how close I can get to 120mph at the strip once I add a 4400 stall. I think I could get pretty close because a friend with the same car has gone 11.8@116 with the same mods but a 3.7 rear.

It would be foolish to pull the heads and not delete the DOD/AFM garbage. Milled stock heads (0.030" is common) and would bring the engine to ~ 11.1 which is stock LS3 compression and is fine with 91+ octane. If you want to keep it mild during the DOD/AFM delete a stock LS3 cam would wake that engine up and drive like stock.
