Which holes to use for heater core cooling lines?

The angle between holes 5 and 1 is to sharp.

Would it be alright to connect 5 and 2?

3 will get a 90 degree fitting and go directly to the heater core.
4 will get a straight fitting and go to the heater core. 

Then put a plug in hole 1


 ???

Personally I'd plug 5, 2 and 1 then use 4 and 3 for the heater core.

1 and 5 are where they go. You should use the shorter brass fittings. Look at the one on mine...

Thanks VileZambonie

I'll check with NAPA about getting some brass fittings.  The steel ones I was testing was all the local speed shop had and I was trying to get parts while I was running errands on Friday.

This project is starting to drain me...

You should be able to get a molded hose for it, OR the hose off the donor.
I ran a short section of rubber hose on mine for a while.
