Hello, I'm currently looking for torque specs for my lower/upper intake, and heads. I'm currently running everything stock, stock intake, stock heads, the whole nine yards. I did however get my heads decked milled and shaved 30 thousandths of an inch to raise the compression. Would that change the spec rate any getting them shaved?

I’m no engine builder, so I don’t know if head-milling/increased CR may require adjusting the spec. ?? I'd also check the spec listed on the gasket you choose. Lastly – the stock head bolts are torque-to-yield, so they may be no-good/"used-up".

A quick search found this:

And search around for the proper pattern on the lower intake -- it's not intuitive.
