What plugs do you guys think i should run. Im running a 12.1 355 with trickflow heads. I plan on spraying 150 to 200 shot. Im currently running autolite ar3935's.

I always used NGK TR55's. They are great for n/a motors but I think guys running spray are using TR66's. I'm sure someone else will correct me if I'm wrong.

Non-projected tip plugs, heat range 6 minimum, probably 7, especially if you'll be spraying often. With that much compression, you'd probably need to go to a range 6-7 anyway, even without spray. Good rule of thumb I heard a while back is closing gaps .004 per 50 HP above stock. Ray at Nitrous Outlet (site sponsor) can get you dialed in. Shoot him a pm or give him a call.

Try NGK TR66s, I've had good luck with them. As for gap, I agree with Gojira94. Ray would be the one to talk to about getting you zeroed in.

You also need a gasketed plug for those heads.
