Do some messaging on the heads and shave them to get your comp. ratio up. It will wake that thing right up. Or put some put some nice flat tops in it with the shaved heads. You need to get that ratio up to make any decent HP out of it.

by the time you shave the heads and port the crap out of the stock small ports and install larger valves for better performance, it'd be cheaper to buy a set of aluminum heads, IMO , I wouldn't waste time with stock cast iron oem heads unless you were under class racing rules
