so i had to install new studs for my intake and exhaust manifolds, as the motor i bought didnt have any on it.
i used the two nut method to extract studs from my old motor and reinstall them in the new one.
i drove them in until they stopped (just over finger tight).
i installed the manifold and started to tighten the nuts when i hear a pop sound. i run my finger around the area and feel a slight crack on the top, but as i feel towards the bottom, i feel the grand freakin canyon.

first picture is from above, the other is from below.
can i have this welded? will it cause an issue if i dont fix it?
i really hope my P8R isnt trash now
Might cause issues if it gets worse. I had a block welded so the head is possible, Just need it pulled and checked for deck specs when done.
blocks are cast iron. heads aluminum. the softer metal expands and contracts through heat cycles. much more so than iron. it can be fixed, but must be done correctly to maintain integrity
On lots of cars that is true, but you do know that our blocks are aluminum, right?
Weasel, there shouldn’t be any issue welding that up.
i had it welded.
i decided that since there was going to be extreme heat way off to one side, that i would have the deck clearances checked, things were spot on though thanks EF9.
i had the fabricator add some more aluminum to that spot, since its sole purpose is to hold that stud in place, i figured it couldnt hurt to have more “meat” there.
also found out that my block is indeed the 8.8:1 compression B20B. boosted motor, here i come.
Glad to hear you got things taken care of! The same thing happened to my brother on his freshly port/polished b16 head when he installed his IM. He nearly shat himself lol. Instead of welding we actually used a metal-glaze, somewhat like JBWeld but stronger. It has held fine through multiple heat cycles and has no leaks. Some of those studs don’t have much ‘meat’ around them, as you said. shudder aweful feeling
