how much does ported heads usually run?
im not aware of any heads on the 3400 that work on montes so i would assume its just ported

 

They might be CNC heads, but I doubt it. They're probably ported. Which you could have done for less than $500 including a valve job.

 

what he said. im all for going fast on a budget but i dont think that there package would be a worth while investment. i honestly dont think porting heads and the intake, doing a cam, and headers is even worth the amount of work involved. i mean all honesty heads are where your power is at and if your going to run oversized valves and port the crap out of the heads one would have to assume youre going to want to run an aggressive cam, and thats no fun everyday when the car isnt going to make stupid power. the motors 207 cubes and if it makes 220hp its only making 1.06 or so hp per cubic inch. not really stellar performance if it was 4-500 cubic inch then youre talking. at that point your making more than enough power to really propel the car into some good times.i just think that for what youre going to spend to do it youre better going power adder, different platform, or with a motor swap. i think the l67 is best bang for buck. the weight has to be similar and in stock form will probably produce equal if not more power then a cammed up ported 3400. not to mention its way easier to pull a motor and do a direct swap then do a cam head swap on a front wheel drive car with the motor still in it.
