Heads or Cam?

[dan_iowa76]

Hey all:

Just mounted some machined stock heads for my '88 mustang. They were done by a reputable shop- ported and polished, with oversized valves and converted to stud mount. Also just put in a B-Cam and converted to MAF just to complicate things are much as humanly possible. Car is running like crap- I checked the MAF computer, put in new injectors, and tested the harness for continuity. Also timed it several times and found that 16* advanced works best. Anyhow, it runs like shit so I did a compression test today and here are the results:

1-150
2-0
3-0
4-150
5-120
6-0
7-150
8-140

Car never makes any bad noises- just missing on 3 cylendars big time. Believe it or not, it actually does have decent power at hight rpm. Why would these valves be hung? If those oversized valves hit the pistons, would it be audible? Retorque rockers, take the heads off and look, drive over a cliff? V/r
