Are you talking about the 305 or the 350 vortec heads? The 305 heads will cost about $250.00 used, and the 350's about $100.00 more.

Getting to the point, just a second. For about $400.00 or so you can get a set of aluminum L98 heads...much better.


There are a lot of articles talking about the same build up. I'll find the link when I get home and send it to you.
