Blown head gasket!
Im not sure if this is a result from re-used headgaskets and bolts or that i drove the car 10miles hot with a popped heater hose. Lets just say its both!!
This sadens me cause now i cant drive the car, but on the flip side im happy cause ill build something different. ......but with loads of compression!
A few ideas
Stay npi heads but newer 5.4l style heads with bigger water chambers. Ported out and decked .120" just like what i have now. 13.1static. No re-tuning required. Low budget
Switch to pi heads. Try a few new modifications tricks, deck them to be equal to or higher in compression. No re-tuning required. Low budget
Swap to 4v heads, like i want to eventually, but i havent fully explored the 2v heads to the max.
4v B heads, i have evything needed but ill need to fab an intake, which i attempted, but wasn't happy with. Capabilities of tig welding is what holds me back. High budget. Tuning required
4v C heads, i have everything needed including a navigator lower intake. I could build/weld an upper plenum for the lower like most folks have done thats swapped in a 5.4l. High budget. Tuning required.
Im leaning towards a simple rebuild back to 2v npi heads, but am open to others ideas.
