Question
what are the torque specs on vortec heads on a 350 chevy that had regular heads to begin with
You need to consult the little book that Fel-Pro supplies. It has the torque values for all the cylinder heads, and the sequences for torquing. I would think that the torque sequence would be the same, but I would not assume it. Using the right gasket is important, too. A Fel-Pro blue gasket is the only one I would even consider. They a have a tech-help line (check their website) and are usually very helpful. Chevy's performance people (also online) can also probably help.
