I have a set of ported j302 heads and would like to know your input on these heads. I keep hearing they are not good enough for my combo?

yah they're fine. you might want to downgrade injectors tho. 30#'s are a tad much, you won't be making enough power to support them I dont think.

some J302 specs:
1.94 intake and 1.60 exhaust valves (2.02 intake/1.60 on K302)
drilled and tapped for screw in rocker arm studs
accepts stock valve covers, intakes, and headers
exhaust flange has dual bolt pattern for added room for porting
combustion chambers are 58cc
intake port is 170cc
exhaust port is 60cc
uses Motorcraft AG series spark plugs

sound like decent heads to me.
like matt said, injectors are unnecessarily big

the heads are fine, now add a s/c and you'll be fine

There is ZERO, I MEAN ZERO, reasons for using smaller than 30#'ers. NONE.

mattdel

why do you say that? stock 19# reach 80% duty cycle at 275 whp. He's gonna maybe see over 300 with those parts.

btw good luck getting $1600 for a used tranny.

So what if he only gets 300hp, there is a thing called tuning. You fix the amount of fuel the injector really squirts, it doesnt matter if its a 24# or 60#, it will shoot the same amount when the PW is adjusted correctly.

i agree with stinkinlincoln there isnt any need to buy new injectors when he will need a tune regardless. also that some rare parts in your build. j302 heads are some of the first aftermarket heads and then a saleen/vortech intake on top of that.

i hope you werent trying to be a smartass with your comment

Well I do have a set of 19# and 24# injectors but the intake came with the 30#ers and I do plan on SC or Turbo come taxtime so the 30s were put in.
