She runs strong as an OX so I'm not worried about babying her home - I need to know she can make it back here though...

On initial assembly, I onlly got about 1/3 turn.
When I retorqued in the car it was hard to tell, but it seemed like it was more. I could be wrong, like I said, it was hard to tell in the car, especially the ones way under the cowl.

Things to take into consideration:
1) Comp Cams and most aftermarket cams have .030 smaller base circle.
2) Are the heads milled at all? .030? .050?
I recall that a setup with a Comp Cam with .030 smaller base circle and heads that have been milled .030 are pretty much a wash- torque to 22ft pounds and then you are set.. using 7.4" pushrods.
After zero lash (pushrod doesn't move) it should take no more than 3/4 of a turn (90 degrees) to properly set to 22ft lbs of torque. If it takes much less, shorter pushrods are necessary.

Also.. the good oil does make a difference with the valvetrain noise.
Just trying to help... I'm sure Slowhawk can get it where it should be.

We had a debate with pushrod sizes - I think I chose the wrong ones. Tried to get some information from SLP on how much they shaved the heads, but they could only tell me they were 63cc 
Judging be the way she feels, she'll be a force when she right

It measures right around 1.615 from the top of the lower row of bolt holes to the deck of the head.
NOTE- these are 5.3 heads.. same concept applys, though.

Well I currently have 7.300's in there. They are making more noise today than yesterday. I only have about 75 miles on the motor - it is a 500mi ride home so I guess the SS will have to wait. - sigh

Wish I still had the stockers - I sold my stock motor complete
I am going to check them tonight - if I can get them sounding better, I'll baby her home.
