OK guys. Need your input on making a decision. Got a '68 Barracuda with 12 point cage but it is going to primarily be a street car. Currently running a 440 with ported 906s with 2:19 intake valves, approximately 10.5:1 flat top TRW pistons at zero deck. My problem is I currently only have the $$ for either a 500" or a set of aftermarket heads. Which do you think would immediately improve my setup the most? Like everyone else, I just want to go as fast as possible!!! I am inclined to purchase the EZ-1s and build the stroker later to catch up to the heads. I have learned a lot form you guys over the years and really respect your opinions. Im certain I have left out some details, please ask. thanks, Ken
