Wrong Pushrods... So i pulled the driver side head from my Envoy last night because the head gasket blew out. As i pulled the pushrods out I reallized they are all 7.350". I ordered 7.400" pushrods from Texas Speed and they must have accidently sent me 7.350". Unfortunatly I purchased them 3 months and have been in the motor since. When i received them i assumed they were the right ones and installed them.
The 799 heads are stock and have never been milled. I was wondering if i should just get the heads milled enough so i can keep the 7.350" pushrods.
The driver side head might have to get milled just a couple thousands anyway to clean them up (if they arent warped). The engine is a '06 LH6 with DOD removed/replaced with LS7 lifters. Its basically a 4th gen, 5.3l aluminum block with flat pistons and 799 heads (similar to 243's). I think the compression is between 9.7 - 10.2 not sure.
Any help is appreciated!

From my first MS3 cam in 2005 to the parts I last ordered for my Envoy, and everything in between, Ive received nothing but excellent service. I wasnt expecting a response from Texas Speed but even then I would still say "Don't Mess With Texas!"-Speed 
Here is the cylinder head when I pulled it off yesterday. I took it to a machine shop and it may just need to be resurfaced to clean them. Gonna have the valves checked out too...
