I see you used ARP head bolts, why didn't you do that for the mains? Since it's a aluminum head you better stud those rocker bosses.

. When it comes to the mains, I just used what Russ provided me for them. When it comes to the heads, I am using ARP studs for the rockers, ARP-200-2403. with my HS rockers. I am not sure what you mean about the rocker bosses.I see you used ARP head bolts, why didn't you do that for the mains? Since it's a aluminum head you better stud those rocker bosses.

It was in response to Wazzu's comment that Edelbrock re-inforces their rocker boss'es but that wasn't the point
I know what your point was. My point is that if you don't think Edelbrock engineers thought of this, or you have first hand experience/knowledge of their heads failing by pulling out rocker boss threads, then you should be calling Edelbrock and sharing that information.
Sorry for the dumb question... If it's to remedial just ignore it please.
What is the reason for the aluminum head? Cooler intake valve temps or something? Does it show higher compression without pinging?

Did you check your lifter pre-load? I originally had to shim my HS rockers, later I purchased some new 3/8" chromoly pushrods in the correct length. The new pushrods also got rid of a little clatter in the valve train.
As I also live in California I am curious if this engine when complete will pass an emissions test or is this "off road only".
It will pass emissions. They pass the smog test, and visually it looks exactly the same as the 4.0.
