I assumed that when I switched from my b18c1 bottom end to a b18a bottom end w/my b18c1 head that I'd need b18a/b headstuds, but I've read a couple of posts on here (archived) that said to use b18c1 studs, so which is it?

 

B18C- anything headstuds

 

thank you, due to the height of each individual series of head, correct? the block end is the same (threadwise) to my understanding
