but got some head gaskets 10.42 at 130 i had my wastegate plumbed wrong 30+ lbs and got in it a couple of times before i hit the track..no knock but the stock gaskets didn't like that..i ran 24 lbs on this run. the very first run the car it was trying to blow the dipstick out i knew i had a problem but figured i would run it till it pushed the head gaskets out..got 7 runs in the 10's before they let go..going back with cometics...these are forsale by the way ..........Bob
