Well, i had it running a lot of time already, i think something must be damaged already, but i love this car and i want the original engine in it, so i will always give my best attempt to stay with the original head and block.
I will unmount the head and see what happened there, hope i'll be lucky cause before i started the engine i spin the crankshaft lots of times by hand and the engine was free.
The head Gasket was a three layers one, it actually seem very similar to the original one, i can't tell if it was thinner...
Sad sad thing this, but may it only have some bent valves or anything, may God wants the pistons to be good.
Thanks in advance for the info mate.
