01 block, 99 head, supertech valve springs/retainers with 97 ECU?
In my search for a motor to replace the blown one in my 97 NA, I came across someone selling their motor for a decent deal. I just wanted to verify as to whether or not the motor would work okay with my 97 ECU for track use.

From my understanding this set has significantly higher compression and head flow than the 94-97 motor that requires at least premium fuel.
I wouldn't have a problem with that, however before I go forth and purchase it do you guys think the motor can be safely put in my NA and run reliably on the track using the stock 97 ECU? What would be the downsides of doing so and what are some things you'd recommend looking out for?
If its not a good idea, I have no problem waiting around for a simple 94-97 or 99-00 replacement.
Thanks in advance,
