I have a 6 bolt with a 7 Bolt head. Arp studs and MLS gaskets. Fp black with interior Al waste gates. I've had multiple head gasket leaks now where the cylinder pressure starts pushing coolant after a few hundred miles of hard driving, especially when it's hot outside.
One used cometic failed at 25 psi, now a brand new Mitsubishi MLS failed at 30 psi with a freshly ported and surfaced head.
Will l19 bolts solve this problem?
Could it be minor warpage in my block?
Or is it excessive backpressure from pushing my imbalanced internally gated turbo too far?
Please share your thoughts, opinions and suggestions to help me solve this problem so it doesn't happen again when I install my s200sx-7670 twinscroll t4 turbo and try to hit 35 psi.
