So stock TTY head bolts amd stock head gaskets correct? Lifting the head(s) at 800whp on pump gas is not surprising to me. Actually surprised it lasted that long. Blaming the tune would be speculation. I dont know shit about tuning so i have no opinion on that.Bone stock aluminator. 93 octane with a bottle of boostane shot every fill up. I never let the tank get below 1/4 before I top if off and add another bottle of boostane shot.
I don't have any e85 stations near me, thus why I asked for a tune that would be safe for 96 octane.
I'm still waiting to hear back from Holbrook for the quote to repair, but I did ask about doing ARP head studs, cometic head gaskets, and total seal rings for the rebuild. I'm hoping those and a hone job will get it back together and not require new pistons.
