Someone on another forums told me that you can use the Sohc Ps Lines and use them on a dohc, but you'll need to cut them and stuff.
here is the post
"A/C is junk... you don't need A/C to run. You would probably need a TB. The PS lines are easy... use the sohc lines, cut them accordingly, get some fittings and a flair tool and you'll be set. No need to waste 160 bucks when you can do it for like 50 (assuming you don't have the tool's to cut the line and make flairs)."
Is there a write up on this or any type of information on this?_________________
