well i have a b20a wich is a 88-91 prelude engine. my dilema is its fully built with copper o ring. i want my car to be driven hard as a daily driver. my problem is its bored out to 84mm. i want to use a stock type gasket vs copper cause this is gonna be daily driven. now honda makes a b21a wich is like the b20a but bore out to 83 instead of 81. either way i've been told u cant get a stock hg bored out to spec cause of the material. being my car is rare in the import seen nobody has my gasket readily available in different bore sizes. so is there a co. that could use my stock hg and make one where they can bore it out to 84mm. i do have a copper headgasket with the right bore but dont want to use it cause i heard nothing but bad things about them for daily use. any suggestion or info on place i can get to make me one would me much appreciated. as if i would have none this i probably wouldnt have bought the engine. thanks

 

ok just got off the phone with cometic and they said they couldnt have me the only thing they could do is send me a b20b/z gasket but my engine is nothing like them. they said i would have to get like 25-50 people to want one before they would custom make it. i do have their request form form a custom hg thoguh. also gem told me that i couldnt use the stock gasket of cause of the material it isnt the same material used with the newer hg that honda use
