What are all the available heads that directly bolt on to the b20a5 block and wat are the compression changes? please

when kept matched yes.But bear in mind that the compression numbers (CR) are more down to the pistons used than the head.
Took the words out of my mouth. Those are the only two head/block swaps that I know the results of, idk if the a3 head on b21 block would be any different than an a5.when kept matched yes.
but the heads have drastic differences too. all b20a series heads have the same combustion chamber volume, at around 47cc's, and all b21 series heads have the same combustion chamber volume of around 51cc's.
so using a b21 series head with b20 series pistons will lower the compression from stock, and using a b20 series head with b21 series pistons will raise the compression from stock
that only works with the crv b20 block, not the prelude b20 block. two completely different motors.but if you are going to do a head swap b18 is the best also known as the frankenstein b20 block b18 head. the best of both worlds the tq of the b20 and top end (v-tec) of the b18. Just IMO's
lol thats funny. tis true sometimes though lol.Yes, I knoe the b20a and b20b r two different motors and it is very pausible, because I have seen,driven it and loved it. My friend special (nickname) Has it and it's a blast to drive it is a b20a5 block and a b18c head therefore (B20 v-tec) and hes not on this site because HE thinks NOT I think 80% of the people on here r retarted.
