I am going to install the cc306 soon and figured I might as well change the plugs while I am installing the lt's...what plugs should I use with this combo? I won't be spraying for a while but wanted to go ahead and change the plugs while they were easier to get to. thanks

 

If you are only spraying 150HP, just throw some TR6s in gapped at .035-.038.

i made 510 rwhp with a 150 shot and this cam and some good heads

the cam loves nitrous

 

ngk tr6 or autolite 104

 

I am using autolite 104's gapped at .037, but I am only spraying 100 shot on the 306, when I move to the 150 shot I am going to change the plugs to Autolite 103's at .035
