Running valve lifters with Mk5 TP cams

Thanks John,
Do you know the duration and overlap?

From the graph I got from Terry, duration, at .020 list, looks like 290 degrees. Overlap, at .020 lift, looks to be 80 degrees.

Is .020 lift the suggested point for degreeing these cams? Most cams are .005 or .010.

I really do not degree cams. I make sure that there is equal lift of both the intake and exhaust valve at 4-5 degrees BTDC. Everything else will take care of itself.

Hello John,
The directions I have from Terry are as follows;
Rear cylinder, Inlet Valve open .170'' at TDC , rotate engine 50 deg + 360 deg. Then the front cylinder Inlet Valve should be open .170''
Hope that makes sense?
I'll will be timing an engine in the next 2 weeks and I'll let you know how I fair.
Cheers

This is in his words ( MK5 cam, they should be set at inlet opening at .170" lift at TDC )

Look at the graph for the MK5 cams. They show equal lift at 4-5 degrees BTDC. If you have this everything else is unnecessary.
