Does anyone know if there are any bigger heads that will fit on an 1986 4 cylinder cav if so please e-mail them to me at the-guy1@hotmai.com i was wondering this because heard that some chevy heads are interchangeable and if they are mabe i can put a v8 chevy truck head on a 4 cylinder and pull more horsepower and since the head is stronger set a turbo at a higher psi setting
are you seriously asking this question? This is about the dumbest thing I've ever heard. If its more psi you want you should try changing your headlight fluid.....I did that and gained 8 psi under my weak 4 cylinder head made for a 4 cylinder.
You've already asked this question in another thread. And it was answered.

In fact, you've started two other threads asking the same question. I guess you'll keep asking until someone gives you the answer you want? In that case, you need to contact Brodix and ask for a BB3 XTRA cylinder head. Get the 366 cc intake port version, and tell them you'll be running it with a stock or close to stock cam and compression on a 2.2. I'm sure they'll set you straight.
