B-SERIES headlift question
Okay here is the deal...
A couple weeks ago I was on the dyno and we completing close to 50 runs. On two of those runs, the overflow puked on the dyno. Compression in the motor is perfect. No oil in coolant, no coolant in oil. No smoking. The overflor suggests headlift but I don't see how on 2 out of 50 runs at same boost level. I am thinking maybe the motor became heatsoaked. I have ARP headstuds and a GE HG, with a stock cooling system. What do you guys think?

Re: B-SERIES headlift question (Boostage)
Yes sir, they should be. I torqued them initially when the Hg was installed and re-checked them a couple weeks afterwards.

The overflow only happened on 2 runs about 2 weeks ago. It never happens while just running the car. It is a drag car that I can't exactly just drive down the street. No leakdown test yet, don't have a tester.
