Hollow stem valves

rx dealer · 07-14-2017, 11:21 AM

Jaf, I bought a set manley solid valves for my LS3. The hollow stem were 6-8 weeks out and $250 more for a savings of only 9 grams a valve. that might seem little but x 16 valves and that adds up. So the new valves, heads,cam, lifters,rockers along with the factory hollow stem valves all went on a spintron to see where i stand and valve control was good to 9400 RPM. on both solid and hollow stem. point is I don't think it matters. I was worried having heavy valves but the spintron proved me wrong. I did find out that my valve springs were too heavy on the seat. I hope this helps...Luke SS 311
