I spun a bearing in my LS block, and found a B20 block locally that I'm gonna pick up. I'm gonna throw the LS head onto it for awhile until I can go B20/VTEC. Now my question is which headgasket do I use, the LS or B20. Is there anything else that I would need to swap it over to the B20 block, there aren't any sensors I need are there?

B20 block, LS head.
TIA

 

need a b20 headgasket because the b20 has a 84mm bore compare to the ls 81mm
ls and b20 everything else is the same.
the only difference is the bore

 

b20 gasket and all else is plug n play.. good luck man..

 

Ok cool, those were my thoughts exactly. I figured the headgasket would be the B20. Thanks Guys, just needed confirmation.
