Ok, so, I've a 2007 charger r/t. 170k mileage. I'm getting ready to get a valve job done. I'm wondering if there were any upgrade suggestions (anything to improve performance) that could be done during the job that wouldn't break my other leg, the job itself (if all is well) is fairly expensive for me... But I have a little room.

 

I think I would just do a long block at this point and also freshen up the transmission as well....

Probably needs a set of rocker assemblys
