GM LS2/LS6 Stage 1

PN: TEA-OEMLS2ST1-CUSTOM
GM Factory LS-2/LS-6
Our stage 1 cnc program is built using our latest valve job and port design for the 243 or 799 GM cylinder head castings. This version is designed to work with the stock 2.00-1.55 sized valves and is very popular with the Z-06 crowd who wants to keep their factory lightweight valves. We give your heads a full cnc port job, custom 4 angle valve job, backcut the intake valves, hand blend the porting and valve job together, flow test (sheet provided), flat mill, and assemble with .650” dual springs and Titanium retainers.
