If you really want to do the right thing, start with reading up on head porting. David Vizards book will hep get you started. It gives you alot of theoris on air flow.
How to Build & Modify Chevrolet Small-Block V-8 Cylinder Heads by David Vizard Yes it is about Chevy heads, but there is alot of good info in there.
Porting tools can get real expensive. The Summit "kit" is too limited to do a good job. You also NEED 6" shank double cut carbide burrs like these:
Summit SUM-900640 - Summit 3-Piece Ferrous Deburr Kits - summitracing.com If you do aluminum, like the intake manifold, you will ned this style:
Summit SUM-900630 - Summit 3-Piece Non-Ferrous Deburr Kits - summitracing.com I also really like the Makita electric die grinder. It is affordable, and lasts a fair amount of time.
Makita GE0600 1/4" Die Grinder Sometimes they are crappy right out of the box, though. Use a dimmer switch for a light and wire it in so you can turn the speed up and down. A router controller works the best, but a dimmer switch works fine. Wear a dust mask, and a face shield. Use a shop vac running the WHOLE time to suck the grindage away, and reduce the dust. It is a VERY dirty job, and VERY time consuming. Your hands will be numb for a week after spending 8 hours on ONE head (you have two, remember?
) I rough in the valve bowls/ ports first, then cut the seats, then finish the bowl to seat work. The smoothness of the port is really insignificant to flow. If the roughness is less than .005" deep, it will have virtually ZERO effect on total flow. The sanding cones are a great way to find high and low spots in the ports. If you run alky, there "might" be some gain in leaving the intake ports a little rough. Spend hours and hours reading up on how good head porters do things on speedtalk.com. Darrin Morgan (Prostock head porter) gives LOTS of advice. BUT.........reading about it and performing it, are two COMPLETELY different deals. It takes many many years porting to get a handle on it. Just opening up/blending the valve bowls in a Buick V6 will net you about 65-70% of total porting gains available. After your first set, you will understand why it costs so much for a good set of heads. And, you will probably NEVER want to do another set as long as you live.
You have to look at it like art work. Creating a master piece.:smile:
