I just installed a new cam, (comp cams XE268). i added lifter preload using the method where when the #1 intake valve is open, adjust the #6 intake vavle, adding 1/2 turn, maybe alittle more.

when i finally fired up the motor, i had valve noise something firece. so i ran the motor for the 30min to break in the cam and lifters. then i changed the oil, and thats where im at now.

so how do i lash the valves. its almost impossible to loosen one, and tighten it untill it doens't make noise, when they all make noise.

someone help?

i need to get the car on the road tomarrow morning.

With intake off to watch lifters, I did mine like this:
Bring piston to TDC on the firing stroke. Opposite lifters will be rocking ( intake opening, exhaust closing). Example #1 on TDC, #6 lifters rocking. Adjust lash on both of the #1 rockers by getting a bit of turning resistance on the pushrod. Then turn down however far you want to go no more that 1 full turn. I went 1/4 turn. Most say 1/2 turn. Rotate crank 1/4 turn and do the next in the sequence.

1-6, 8-5, 4-7, 3-2, 6-1, 5-8, 7-4, 2-3

i think i got everything fixed, i went and gave all the rockers another 1/4-1/2 turn with the motor running, and the noise is all but gone, as for getting the car stared, who would have thought that with a new cam, my carb might be a little lean. after richining it out quite a bit, it runs fine.
