Unhappy Compression Test Result

I'm thinking with these results the head gasket is definitely blown?
Could the pistons/rings also be damaged?

Driver Side (left to right)
Dry/Wet
#1 125/175
#2 165/195
#3 130/170

Passenger Side (left to right)
Dry/Wet
#4 90/120
#5 90/120
#6 210/225 The coil pack on this cylinder was covered with oil with melted chocolate like consistency. All removed spark plugs was covered with oil.

Yikes man, those are terrible, terrible numbers. You know you have a definite problem, so usually the next step is a leak down test, which will tell you if it's valves, rings, etc.

You have 3 options:
1) Buy a low mileage motor. Try car-part.com. I think last I checked, they had some on there for $1500 or around there.
2) Rebuild motor with keeping factory rods and probably even your pistons. You probably just need the block bored (or just honed if you're lucky) and new rings, along with all new gaskets and all that jazz.
3) Build your motor for an insane turbo setup. This will cost a lot, of course, but some people use a dead motor as an excuse

But making N/A power is so expensive, haha. If it's what you want to do, more power to ya. I remember 6 years ago, I wanted a crazy cammed 4.15L stroker, but the power/$ for that is just nonsense.

sure I am. Its an 03 with 80k miles. The cost of a motor is like 1/4 the cost of the entire car, esp if you cant do your own work.

Still haven't completed a leak down test but I'm assuming the worse at this point. I'mdoing my research but I'm a complete noob when it comes to this....
I'm getting quotes from various companies from 2k-4.5k for a new engine...???...I'm also looking at sites such as Z1/Forged etc for their built engine but unsure which route to go. What should I look out for when looking into a new engine.... mileage/condition/warranty???

Anyone familiar with Rydellpowertrain.com? Got a quote for a long block for 4.5k with 3 year 100k mile warranty
vs. stage 1 long block from Importspartpro.com at 4.5k.
