New cam and springs, will rockers and pushrods hold up???
Ok, I have a stock 6.0L out of an 06 2500 HD. This LQ4 engine only has 19,000 miles so I am trying to make this last for a while and dont feel like messing this thing up. I installed a comp cam 232,234 595, 598 112LSA. I used crane dual springs with steel retainers and left everything else stock. I dont plan on turning this engine past 6200 but what does everyone think is safe. I am using a mighty demon 750 and a 6 speed all goin in an S10. This engine has not yet been fired.
As far as timing, I just simply lined up the dots with #1 at TDC and Tq it all back together.
As far as the heads go, Installed springs and retainers and Tq all back down.
I'm fairly sure I have plenty of piston to valve clearance but I am woried if the stock pushrods and rockers will hold up to it. I could get some comp pushrods for a decent price but I dont know if I should keep the same length or what. Not really wanting to spend alot on rockers but if its a must then I gotta do it.
Any help is appreciated, Lee.

Actually with a bigger lift cam you want a little bit longer push rod to make up for the base circle diameter decrease. I would through in 7.425 chromoly pushrods from comp just to make sure it doesn't sound like a sewing machine. Definetly do not go shorter unless your milling the heads. all in all youll be fine with 7.4 but i would get the .025 longer just to be safe. Have fun!
