I put these in and the cam/specs were done by Pat G and Geoff so I know its all correct.

Question is on spring install, do I simply torque all springs to 22ftlbs? Or do you rotate the crank, torque, rotate crank, torque, as you go for each cylinder?

Right now they are all torqued to 22 ftlbs with the crank left stationary.

Thanks for the help. Never done a cam or springs before.

Are running an actual L92 engine with VVT? Or your swapping L92 heads?

L92 and kept the VVT with new cam and VVT limiter insert. Not swapping original L92 heads.

VVT cams dont typically require dual springs...

I think you meant to ask about "rocker arm torque" as well. I have always just torqued rockers to 22lbft, done it tons of times and never had an issue.

Cool. I thought I had read somewhere to rotate the crank as you go but I certainly don't want to tear into it again if I dont have to.


Thanks.

Next step is putting it back in!

Take the valve covers off. Spin the crank and re-torque. Can't hurt.
