I'm getting ready to install a comp vvt cam in my 2011 Escalade. It's a 214/226 .500/.500 115+6LSA. Plan on upgrading the springs. Probably a set of PAC 1219x. And a DOD delete from Texas speed using the ls9 head gasket. Unless theres a better head gasket I should use. Also going to do some long tube headers. Probably a set of speed engineering 1 3/4 and ory. I know they'll require some modifications but that's fine with me. Should I upgrade the pushrods? I have a set of comp 7.375 from my Sierra build. Only plan on running it up to around 6300rpm. Any thing else I should look into? I'll do the tuning with my efi live and a wbo2 is on order as well.

 

The mild lift would lead me to say no need to change the pushrods unless you need a different length.

 

I'm also switching to comp lifters and not sure if they require a different length pushrod like the ls7 lifters can

 

Yep lifters are a must.
I went with Morel lifters on stock length pushrods
