Spark plugs??

We have started working on my new setup and while the engine is going to be out I want to go ahead and replace the spark plugs. I didn't know if I should replace them with stock ones or another kind or brand. Here is what my set up is going to be:

MS3 cam (237/242 .603/.609")
CNC ported LS6 heads
LS6 intake w/ ported TB

You can also run the TR6s without problems. Since you are adding close to a 100+ hp they won't hurt anytthing. I ran them with my H/C package before I sprayed my car

+1 for the TR6 plugs. This is what I run in my heads/cam setup.

what is the difference between the 55s and the 6s anyway. the 6s are for more power or spray? and the 55s are for naturally aspirated motors??

For a heads and cam car, you would want to go with a TR6 due to more horsepower than stock.

Both run colder than stock plugs. 6's work very well in boosted applications because of the higher compression that's seen (no flameouts). 55's are a step down in cold range.
