sorry if i didn't use the search button. But this is sort of an emergancy. Need help from the gurus.

B16 bottom end mated with a gsr head.

i need to know which headgasket to use and which head bolts to use.

Final question. Is there any sealing problems with the type of hybrid swap?

Thanks in advance for any help posted. I do normally use the search, but this is a rush help needed

thanks
