    JMO on this for what it's worth, do your home work and be SURE you are ready to commit to the parts involved when you buy these. You will probably need special pistons to use them since they have an 18 degree valve angle, and I believe that the cam is also specialized for SB2 heads. Do not quote me on that however. With boost these should run insane times, but based on everything I've read about people tuning them be very conservative on the timing initially. Considering that there are a ton of heads out there that are "conventional" 23 degree and flow insanely (especially if you're looking in the 280CC range)

    if used on a standard sbc block dbl offset lifters have to be used but can use a regular cam,only downside that i saw was some of the sb2 stuff needs atleast a 4.160 bore for the valves to clear the bore.and yes they do require special pistions

    if i do a sb2 setup it will deffinatly be with boost

    i was just curious if 2k was a good price for a set of heads/rockers.springs etc

    There is a member on here that goes by Jackstand and he runs the sb2 heads on just turbo malibu. It is a fucking animal to say the least. YouTube his name and watch his car drag the bumper a few time out on the big end. Custom pistons are required, custom lifters I'm not so sure about that. Has a designated intake as well as exhaust port is different then standard. I also think they are a 13-15 degree head not 18, but don't quote me on that.

    I'm no expert on those heads but I can't see how they'd work with a standard SBC cam. The intake and exhaust valves are switched around on the outboard cylinders, so the cam lobes would need to be rearranged to match.
