How would WP S/R Torquer 305 heads do on an L98? What kind of problems would there be?

 

If they aren't already, port them ( http://www.sa-motorsports.com/diyport.htm ).

Unshroud the valves a little more, which will increase chamber size a bit. Use a thick composition gasket, and compression will stay in control.

By all means, DO NOT use domed pistons. Flat tops with valve reliefs at most. Even mild dished would be okay (don't need to increase chamber size or use thick gaskets if you go with dished pistons).

I haven't done it, but I've been thinking/researching a 350 shortblock using the rest of my package for some time.
