Ok another question about the heads!
I was looking through that motec page and I found these two vortec casting numbers!
10239906...(year)96-up...350.........."Vortec 5700", "L31", 64cc chamber, 170cc intake port, 1.94"/1.5" valves
And
12558062...(year)98......350..........L31 Vortec, truck, 64cc chambers, 1.94/1.5, 170cc intake port
Whats the differance?
