digitizes the heads. One has heads by Gary Hettler, one has heads
by K.B. Racing(Line Performance), and one has heads by Jeff Taylor.
Which one becomes the new standard? J.R.

None of the above. You can only assume NHRA has been scanning untouched OEM heads, you know "stock".

LOL........It sounds like there won't be as many stock racers crying to get an increase of the Quota so they can enter to me. At least the really fast ones.

How will they deal with intake manifolds that have no 'spec'?

Tough to put the genie back in the bottle..... -Al

They may not have a "spec" but they sure can scan them as well. I guess Cdn intakes are going up in price. LOL

Anyone who actually encounters the process of having the head scanned @ Indy want to volunteer to inform the rest of us how it's actually put into practice....

I'm new to this game, but have been lead to understand that in years past certain things became "Accepted" based on the first head or some other parts because NHRA didn't have an OEM one to spec so they spec'd off the first one through teardown.. Meaning the "scan" could be based on the guy who gets scanned first not the actual untouched head... I have little faith NHRA has sought out each and every head in the book to scan them prior to using this new technology.. I also have little faith the Manufacturer's..those that are still in business would provide them with a CAD file they could use to compare a fresh scan to.. So what are the basing the legality of a scan off of?? They may have picked up scans of all allowable "Showdown" cars as that is only a handful of heads to scan.. but for the rest of us this seems to be a little less enforceable.. I can tell you if my untouched heads are deemed illegal because another car that had heads that had been massaged on gets scanned first, this technology will in fact be useless to me...

just my .02

Agreed. But like the heads...how would they determine what's 'stock'?

Sounds like Wesley will be at Indy.

I think Wesley will be at Indy.

Be thankful they're taking this a bit more seriously. They could solve this problem with a stroke of their pen. Imagine a rule book entry like "stock intake and exhaust valve diameter required; any other head modification allowed" and "any intake manifold or modification allowed as long as the material matches the orginal and it fits the stock carb".

I think more races are won and lost on the drag strip than in the teardown barn.
