SBC stocker replacement heads?

rboyle · 04-03-2015, 08:36 AM

Are there any NHRA approved stocker replacement heads for the SBC? I see them for BBC but why not Small block too? All the ones I'm finding are either modified or cracked or warped because of thin castings. 993's or 493's seem to be preferred over the 881's and 882's but right now I'll take any that are ready to go. Unless someone knows of a replacement?

Look around in this site. http://www.classracerinfo.com/

There are "some" approved replacements now and I expect more will be added all along. You are correct in that the factory casting while they can still be found are fading quickly.

It seems reasonable that in a few more years replacement heads will be normal procedure.

In addition, the overall cost will be less and the performance will be better.
