i hear that milling your head and using 1 layer head gasket to bump compression requires cam gears to bring the cam timing to feel a difference if so how many degrees do i advance with .030 head mill and 1 layer head gasket? thanx in advance 4 ur help!

 

it is not for "feeling a difference" it is to make sure you can set the timing accurately now that you have removed so much material.

 

Every 0.020" decrease between the distance of the crank and cams is 1 crank degree retard on B series motor.

 

advance both cams 2 degrees and you should be pretty close, you can accually use the plate that goes across the cam caps, (if you are using oem cams) there are 2 holes on each plate and one hole on each cam,
1)degree the crank at tdc
2)put the cam gears on 0,
3)put timing belt on and make sure its tight
4)spin the the motor 1 full revolution back to tdc on the crank
5)on the iner marks of the gears the ex cam should be lower(retarted) than the in cam
6)loosen the cam gear adjustment bolts
7)you need a dowel pin that fits the plate and cams tightly, put the dowel pin in the plate and spin the cam until it falls in place, you shouldnt have to move them more than a couple degrees, then tighten the adjustment bolts.

 

ok thanx, about how much hp will i gain from doin this whole head milling and 1 layer head gasket job?

 

is cam timing the same as distributor timing??

 

Cam timing is changed with cam gears. After you adjust the intake cam, don't forget to do your ignition timing as well.
