It's hard to find high RWHP cars on the street that are willing to run from a dig. But I don't mind. I ran my buddies Saleen with some kind of Rousch package last night from a dig. In the end it turns out the same. My Z faster than the blown Stangs.

Edit: Here is an awesome post from our very own T-Shep that I have had bookmarked a few years back on AFR plugs for each CR/shot size:
Here ya go. I have used this chart for my AFR heads for a long while. These are the gasket style plugs.
Heat range //////////////////////////// NGK ////////////////////////// Autolite
stock heat(5)10.5:1 compression n/a...2382 ..............................AR3937
1 cold (6) 11.5:1 compression n/a.....5553 (BKR6E)...................AR3936
2 cold (7) 12.5:1 compression n/a.....4091..............................AR3935
3 cold (8) 150 shot.........................4554 (R5671A-8)..............AR3934
4 cold (9) 150-250 shot..................5238 (R5671A-9)...............AR3933
5 cold (10) 300 shot........................5820 (R5671A-10).............AR3932
6 cold (11) 350+shot.........................?................ .................. AR3931
I have been around 12.5:1 compression so I would use a 7 for n/a then colder per size shot I used. You guys with less compression need to scale back one size or two.....meaning if you are 10.5:1 compression use the 5 heat range for n/a and a 6 or 7 for nitrous.....etc.
Good luck!

But to answer your question, "no", TFS heads are not that picky.

Yeah I did. Never really got a good pass though. The track was busy and I think going with skinnies for the first time along with this new power combo the car was a whole new beast to figure out. I was happy with my times, and they would impress some on here that believe my car is only good at roll racing, but I'm gonna keep what I ran quiet until I get some more runs in and make a pass I think the cars potential has in it.

Indeed.
Everyone who has been to a track before knows that you will NEVER run your cars full potential the first time to the track on a new combo. Too many things change at once, and settings and techniques that worked perfectly before may not work at all on the new setup.
