Hopefully in the next couple of weeks I'll finally get my VQ heads back (they've been in the shop for 7+ months !!!!!), so I bought this course but sadly we didn't get an example (yet) of a VVT engine.

I presume I'll just have to open up the cam sprocket phaser and jam it fully retarded then advanced to get my readings ?

Lastly, any thoughts on how much clearance would be suitable (it's an NA track/street car)?

Hello i would normally be looking for a min of 0.060 inlet and 0.080 exhaust. recommended is 0.080 and 0.100 it would gus depend how far you want to push it. also things like rod material etc
