Hey, i found a great deal on a b18c1 fully built bottom end. right now there is a b16a complete motor which has a blownhead gasket and i will be using my trans and head on the b18c1. First question is will the head be ok on that bottom end? and what headstuds do i order? it seems as though the b16 and b18c have different part numbers...? Or would it be best to search around for a b18c head?

 

gsr, the b16 are shorter

 

but ill be able to bolt down my b16 head into that block and not hurt anything right? Why are the gsr studs longer? taller head height or bolt goes into the block further??? can only go either way i suppose lol. thanks

 

I think it's because the GSR block is taller than a B16A block. I'm not sure though. I was searching for answers to the same question that you had.
