what's the difference b/w the two??

i'm thinking about getting a b20 HG since its bored to 84mm already and modifying it to fit my GSR 84mm block..

from what i remember, the only thing different is the dowl pin size on the HG's may not be the same size.. I had one of each but forgot to put them up against each other to compare and threw out the nonvtec HG already..

what are your thoughts on this..??

 

why dont you just get a gsr headgasket that is 84mm. many afermarket companies have them.
