update. I'm replacing the head gasket again.. the head gasket I bought on ebay was very different in quality from OEM..
So my advise is Please buy OEM when it comes to head gasket... it's cheaper on ebay but your end up replacing it again...

OEM had more material and thicker...compared to

ebay item...

You are making sure to replace the head bolts each time as well yes?

With the engine in the car it's a two weekend job. Impact wrenches and air ratchets speed things up considerably though, without them I'd add an additional day and I strongly recommend draining the AC and coolant and taking the front off just for the sake of having more room to work with the timing components.

In a shop with an toolie to pass you stuff it's about an 12 hour job.

The shop did a cylinder leak test with the new head gasket...
I'm worried about the 20psi. what does this result tell me?

1st cyl 7psi
2nd cyl 20psi
3rd cyl 8psi
4 cyl 7psi
5 cyl 10psi
6 cyl 8psi

Piston rings are the next culprit if you just changed the head gasket. What were the numbers of a compression test?

I do not have heat at idle.
I did use a no spill rad funnel.
When you have heat at idle the system is bleed. The heater is the highest point of the coolant system
