Im looking for a spark plug reccomendation for my setup. I have an lt1 383 stroker. AFR 210cc heads. From the searching i have done i've found that i need a gasketed plug? I would like to stick with ngk as im currently running the tr6 plug in my stock motor and have to great success. The new motor is built for boost. 8.5:1 cr. I will be turbocharging next year but i am going to run it na this year. Thanks in advance.

Stick with the NGK's as they are the best in LT-1's. Here is a link to what AFR recc's and make sure to go with one that is 1-2 heat range due to the blown setup. FYI - I have splitfires in mine with AFR 190's (older style) and never had a problem. Would like to go with NGK's but to much of a PITA to change and not worth it for me. Good luck.

Thanks for the replies. I think i'm going to try out the NGK #7942.

 

I use the Autolite AR50 in my car. I like how they have a shortened and rounded strap. when I had them on my 355 with pretty well stock compression I used the Autolite AR3910. I like the cheaper autolites, they work fine for me.
