Yep...I ran Morel 5315 drop-ins in my H/C LS with great results. They have been since replaced by the 6504. 10-15k miles on the setup over a span of 4yrs with a plethora of WOT runs up to 7200rpm. I ran a fairly mild comp XE cam with SLP 1.85 rockers and pac dual .650 lift springs. The heads were TEA ported LS6 castings with the sodium filled valves...she liked to rev.
