Copper Head gaskets and O'ringed block users. Post opinions please!
 

At what power level and boost do you guys use copper gaskets and orings.
I keep hearing mixed feelings and reviews. Id like to hear from some people with first hand experience please. Curious if it works well for yall.

I have used oringed blocks on 4 cylinder builds in the past. I liked them. It rid of the coolant pushing.

I have an oem block and oem headed 5.3 ls engine. I trapped 160 and went mid 8's last season at 3,400lbs. I plan to cut a little weight, get a better convertor, and turn up the boost. I had a headgasket issue once last year and I want to rid that of happening this summer.

Thanks guys.

I feel it's a must on our engines.

Thank you. I am leaning towards it also. Are there any downfalls to it? Is there any bad points of the copper gasket? Does it retain water the same as traditional mls? Does it last as long?
I just ask because I plan to run coolant and still drive it on the street occasionally.
