Re: porting-polishing

The heads were already done when I bought them.
The intake valves are stock size, the exhaust is barely over.
I figured, using it would be better than buying new ones.
youre right though, I forgot, polishing makes the fuel/air mixture flow through smoother and faster, which I dont need at low rpm.
If they don't work well, I mightlook more in to the alluminum heads that are available, but i've never liked the idea of alluminum on top of iron.
440 parts are hard to find.. I've been working on this engine for 4 months now (in what little spare time i have)
