![]() Can't say for sure, but I do believe you probably have GT40 iron heads on that engine. 270 horse with the E303 cam would probably be about right with GT40 irons on it. They out-flowed the stock heads and added about 25 hp or so, although there are a lot better heads out there now, they were still worth swapping out the stock heads for.
