I have a 2004 lm7 5.3 I'm picking up my new heads (stock ) casting 706 I belive. Ported polished and milled. 012 I have been told... now I was told to run 7.35 push rods with a stock gasket.my only issue is down time so I'm making sure I got everything b4 I tear it apt. You guys think these are the rods I'd need?

 

the only way you can find out exactly what you need would be to buy a pushrod length checker and find out before you order. but if you are buying from a good shop with knowledge of these engines you can buy what they recommend.

 

^^^^^^^Agreed. 7.38 is stock, but imo you should be fine with 35's as long as the cam is on the same base cirle as a stock one.

 

Its a tr 220 cam 114and lsa. 551 lift
