[Spridgets] Aluminum Head torque Specs?

[WeslakeMonza1330 at aol.com]

I torqued the Pierce head on my car's engine as per the ARP studs and in  
fact didn't give a thought to a non standard torque for it being an aluminium 
 head.
 
1.5 Rockers run with more clearance than standard rockers so they tend to  
be noisy.  Kent advise 16' for their 276 cam.  DV suggest that 3' more  for 
1.5 rockers = 19'!
 
For the APT scatter pattern 286 and 1.5 rockers I'm advised (by David Anton 
 at APT) to use 16' on the inlets and 18' on the exhaust and I don't make 
any  allowance for it being an aluminium head (maybe I should?).
 
It makes sense to run less clearance on the inlets and I don't understand  
why anyone else doesn't recommend that.
 
Regards
 
 
Daniel

hey all,

I was  hoping someone out there would happen to know the torque specs for 
and  aluminum head.
It's a 1275, I believe a Pierce head. I've run it about 500  miles or so 
since it was installed so,
I figured that I should re-torque  the head.
I went through my personal archives and didn't see any mention of  it.
I've sent an email to the guy that built it, but haven't had a reply in  a 
few days,
and I know many of you are running them, so I thought I would  ask the 
guru's of the Spridgets list.

Also,
I should check the  valve lash also,
any ideas of the clearance for that?
It has a  Kent 276 cam and Titan 1.5 roller  rockers.
It runs great, although the rockers do seem a bit  noisy.

Thanks!

Brian S.
