NMC head question

[WarrenRacing71]

I came across a good deal on a set of Pontiac aluminum head for a SBC. In the rules it says:

1.17 HEADS
HEADS: Aftermarket cylinder heads permitted, but must retain original overall appearance for engine declared. Any internal cylinder-head modifications permitted.

I'm not sure how much different the Pontiac heads look compared to a normal SBC head besides they're stamped Pontiac. Would those be ok to run? Just curious.

The Pontiac heads will be legal for the class.

It was nice to see you and your car in BG.

There was a 632ci powered red 1976 Impala in Bradenton in NPS.

thanks it was nice too meet you. i'm going to try to make it to most of the races this year. hopefully i'll have the scooter charged up for now on. i did more pushing that thing than riding it.

a 76? really.. wow... i'd love to see that. i wouldnt mind going with a big block in mine, but my car needs to be on a diet. 4000lbs w/ a smallblock is way heeeavy.
