pro comp vortec head
 
Anyone try a set of these. Vortec iron heads, 190cc, 64cc chamber, has the 7th bolt hole on the exhaust side. Head is tapped to accept vortec manifold and old style TPI?? Cheap too.

The point of genuine GM Vortecs is they get such excellent flow from only 170 cc. Whatever you found had better be over 270 cfm by 0.500" on a 4" bore, or why get them? If they're over 250 cfm by 0.550" then they're better than Sportsman 2s. Don't ever consider those.

They use that as a big selling point , but all it really means is reg 12 bolt SBC intake will bolt up.
Not that the intake ports will actually match
( without welding to increase port height to match the raised port on the Vortecs)
