Holley must have not updated their site because the new holley heads are 2.02/1.60 valves. The older heads had oil issues so they changed the design. The cam has also been changed but I think its the cam you listed which is the lunati 51014 cam. Cant comment on the kit cause I dont have it, but IMO that holley intake is a HUGE overkill for a small streetable 302. IMO its more suited for ported heads and bigger cams with 6k+ shift points. The holley lower comes set up for a fel-pro 1262 gasket while most aftermarket street alum heads/lower intakes are set up for 1250 gaskets. Fwiw, I run the full TFS combo and like it. I'm hoping to hit the track Wed night in hopes for 12's @ 110. A little more info on your car would be good too, like is it auto or 5spd, vert or not?? Any mods? Later,


Mike

Dont have much done to it yet stock motor, 3:73's, steeda short shifter, off road h-pipe, dyno max mufflers low restriction, me and a couple of buddys dont under stand though it is pretty fast for being stock i raced my friend a few times and he beats me by like to car lengths and his car runs low 13s and my car holds fairly tight until we hit about 80-85, i am pretty impressed by it oh yeah it has a little bit better fuel pump in it. I know the guy who owned it prior to me didnt drive it that much and it was a show car that i am trying to make a go car. I can get the car to chirp the tires into fourth gear


ps car has 72000 orignal miles
