Cylinder head Questions



Well now  that I have found the problem to my watery oil in the 4kqt (Cracked 
Head) I now need a good donor head. I am currently using the stock vacuum 
pump and would like to keep it, my question is what cylinder heads have the 
vacuum pump and the 40mm intake valves? I know the NG type heads use the 
vacuum pump and the larger valves but I don't want to manufature a custom 
intake for the turbo.. 

Thanks,

Scott
