Re: stock head build

porting heads is an art, it takes years of research & Design as well as flowbenches and other machines to get good at it
I've done my own head porting, but I'm sure it is nothing better than what the factory designed.
More than likely, all my cylinders are running all different AFRs now

Ok,

I wanna clear somethin up. All our vendors such as zzp, intense and so on all take stock heads and port and polish them adding their own valvetrains to them.

By porting your own heads, its extremely inaccurate in terms of exact head flow measurement, every intake and exhuast port need to be perfectly tuned in conjunction with the camshaft.

My reccommendation to you if you dont wanna buy a set of heads would be to either take your heads to a machine shop and have them do it for you because at least they will have the propper tools and possible a flow bench to insure flow consistency or if you do it yourself all I would do is polish the ports, just getting all the crap off and getting a nice smooth finish.

In actuality, the stock heads flow rather good, as you can see in my writeup up top, the stock heads have the best exhaust to intake ratio.
