getting ready to swap to the ms3 cam over the winter. i have been looking at ls6 heads off and on. i wanted to know if i would see that much difference or not. also they should still clear like the stock ls1 heads correct. are they worth the price or not? thanks, steve

 

You can get the "NEW", 05 + 243 castings a lot cheaper.
$1095 with springs and stage 2 CNC at Patriot.
Same as LS6 just no hollow valves.
