i was just wondering if the things i was being told were true, i have been told that AFR's are weak heads when it comes to longevity and what not. So if that is true, what are good performing heads that are good for the long haul. here is whats going on with my heads and a compression test. Two didn’t have compression, Here is the draw up #5 cyl had zero compression as well as #4, #1 had 145, #2 had 90, #3 had 115, #6 had 125, #7 had 125, #8 had 120
