Which spark plugs w/ TFS heads?

I put some brand new TR 55 in w/o thinking. Just checking to see if there's a better plug for these heads due to the different valvetrain geometry.
BTW They're TFS 225 on a stock LS2 bottom end, N/A for now.

Did you do the cam also? If so, TR6 would be better. Check them and see how they are burning. http://www.dansmc.com/Spark_Plugs/Sp...s_catalog.html

TR-55's should be fine. I'm running TR-6's but i've also got 12:1 compression

As stated above TR55's will work but i would go with TR6's. What compression are your running at?

Thanx for the replies. I kept stock comp ratio to leave some room for the nitrous later. When I put it on the jug I'll be using the TR 6s.
