Stock 289 valve sizes.
1.78 intake and 1.46 exhaust.
Combustion chambers were untouched.
Not even polished up untill now.
Since the sheetvrolets have been cheating by modifying their's for a couple of years now and NHRA was not able to police it, they have now allowed chamber modifications in Super Stock.
They are soon to be finished and will resemble 351W chambers.------------------
