I ordered a pair of brian crower stg. 2 cams + valvetrain and I have a question about the installation. I talked to a shop nearby and they said they could install the cams, valvesprings, retainers, and older style keepers without removing the head. I read in the sticky for later models that they require new valve seals, as well. the shop told me they didn't want to remove the head and to install the seals they would have to. i got a quote from another shop in the area but it was for about 4 times the amount to remove the head and install everything. my question is I'm wondering if new seals are really necessary on the newer models? In addition, the shop cannot tune my k-pro because they do not have a dyno. is the brian crower kal in kmanager suitable to drive on until i can either get dyno tuned or a street tune? thanks!
