No to various spacers and bigger carb...... time was limited on the dyno. We did jet up the carb several sizes to get the AFR we were looking for.
The intake is port matched to the heads with a little internal work...not much though. I think there is some to be gained with the intake.
My backorder came in after the dyno session so I have a actual Edelbrock Air Gap for it now. Going to hog it out and port match that intake and put it on.
I wont be able to get it back on the dyno but my head will say I picked up 15hp :)
