Now Cal and a couple of others are going 8s with the Champions. This is incredible by any standard. ...do you want to run the increased revs to take advantage of the extra head flow of the S2s? Do you want to do the extra work to get the intake, cam, headers, etc. set up? If you want to go the "ton of boost, lower RPM, bolt the intake and accessories on and go" route, maybe the GN1s/TA heads are the right choice.
Oh..one more thing; Art, you can discount my thoughts if you like since my car(s) haven't gone sub-10s yet. If you do though, I'll have to tell you what I really think of your red accessories under the hood!

Thanks for the opinions, you've articulated what was brewing in my mind. I have to decide whether I want an engine similar to my current one or, as you say, do things to take advantage of a higher-flowing stout head (which I also have on the shelf). My Excedrin budget may be the deciding factor. Yes, I'd like to spin it high, say, high 7K instead of current high 6K. Any header/dp plumbing issue and head set-up work can be dealt with.
BTW, with my LT88, I noticed very little improvement going from a 3" to 4" dp, so I tentatively conclude that a larger exhaust wheel and/or housing is required to take advantage of that change in my combo. I hope to test that this year.
You're building your Stage engine and car, you qualify to respond
. My request may have been rude... consider the source. Feel free to use my accessories against me, perfectly fair game! I know some people believe that what I did to my engine compartment is repulsive, and I understand that. It's part of a pattern of behavior. I think I yearn for reminders of good old parental disapproval.
