Another Vortec head question
I asked a while ago for opinions on Vortec vs blueprint heads and most people suggested Vortecs For a stock/mild 350. My next question is should I stick with gm Vortec heads or go with summit Vortec heads. The only real difference I see on the specs is 64cc chambers for gm vs 67cc on the summit heads. Any thoughts, opinions or experiences? Thanks
