ok hears the deal i just put high compressin pistons in my engine raises the compression to 12:64 and the deal is i am using a auto zone head gasket did not tourq down the head just tightened bolts and pistons dont hit inside the head the end of the dome part is hitting the combustion chamber so i losen the bolts and turn the crank and it freely turns with the bolts loose so hears a pic of the gap i need what size head gasket and were can i get one to fill this gap

 

your fucked

 

12.6 isnt that high of a compression. is the gap level on all sides? buy an oem gasket. your head might be milled or warped because i ran 14:1 compression pistons with a stock head before and it was fine

 

Im thinking your head is warped. Did you torque it in the correct patter? Also did you put the dowl pins in the right area?

 

head is not warped gap is the same all the way around don't know if head is warped bought it from somebody what kinda head gasket will fill the gap

 

then they milled the $hit outta the head ...gl time for a new head
