Default What head

ok so i have a b18a1 motor i'm swapping into a 1990 4 door civic and i want to turn the car in to a drag car so i want to swap the head out on the b18a1 and put another head onto it but i'm really not sure what head i can put on it to gain more power so any help would be awesome. I would also like to know what head and other materials i would need to swap heads like what head gasket i need and if i need to change anything else to do this.

the b16 and b18c's are vtec heads, meaning they wont "fit" on a b18a/b block. You have to get dowl pins put in (you can get a ls/vtec kit with all that stuff) and you need to run the vtec oil pressure line. I think with the b18 non-vtec blocks you will need to put in a knock sensor also

here are some links to good info...I have all these in my favorites cause im thinking of going the ls/vtec way

That depends on a few things. Now I can say that it will put down over 200 hp to the wheels for sure (n/a) Check out this thread and look for builds with a b18a/b block. I say your best bet to get some more power is to use the b16 head not the b18c's.

You have to type in honda - tech where the *** are...
