I'm using an SW5-07 cam and stage 3 head....

I asked a friend who suggested 18thou, but not 100% certain

15thou id have said. So agree with kel, 15-16thou

Roller rockers are always 16 thou

Looks like 16 to 17 thou is the general consensus, looks like i'm going to have an interesting saturday adjusting the valves

[mini_kel]

definately 16 thou with that cam 100%

sw5-07 on standard rockers is 15thou (so the sheet says that came with the one i brought)

With the one wheel off the ground, rotate it and this will cycle the engine allowing each tappet to be adjusted and checked individually.

However, i think this method will only work for car without a limited slip diff......

I stick it in 4th and roll it back and forth... builds up those thigh and calf muscles! LOL!
