Does 220-220-220-230 on 10.5 compression with a MLS head gasket sound good to everybody? Or should they be higher?

Sounds good to me.

Dude. You went 10-5? Sweeeeeet. We're going to have to get all you Tucson guys up here or all us Phoenix people down there some time this summer.

after rebuild I guess that's ok but after it breaks in expects something around the 250s.

I have 10.5:1 JE and I just did a compression test on my engine today and it gots 260s in the first 3 cylinders and the last one well I think i have a bad valve or something got a 30 psi.

Thats what i found during searching. I thought it might have been the MLS head gasket making these numbers. But how long does it take to break in a motor with total seals? 1500?

can't remember it takes a while. Did you have your head rebuilt also? I didn't get even compression numbers until I had my head cut again. after a thousand is supposedly break in but I think it takes a bit longer so yeah 1500 is good assumption or 2000.

I hate all you and you're high numbers... 110 110 95 110 ;(

man you must have massive turbo lag haha, when my engine went I was in the 130s it had like like a mofo i'd need to clutch kick just to get it to boost faster.
