LS9 Lash Caps
Didn't know about the need for special lash caps on ZR1 heads with titanium intake valves. Installed a pair of CNC ported ZR1 heads on my new LS3 Grand Sport corvette. Bought the heads complete with valves, springs, retainers and keepers. The Seller never told me about the need for special lash caps on the titanium valves. The setup ran good for about 6 days. It then dropped an intake valve and totally destroyed the engine.
