Dang, you must have some serious dish on them pistons. Edelbrock casts a smog legal head specifically for the TBI setup. It has 100 cc combustion chambers and still yields only 8.8-1 compression. Edelbrock advertizes it will put you up to 357hp and 475 lbft. That should definatly get you moving, and with a camshaft, you may be able to push it near 400hp. These heads are aluminum and, therefore, expensive. Aluminum is useless at that low of a compression ratio and I would look for a good set of irons with a 100 cc or smaller chamber.
