Porting Tools
Hey there, I port heads on pretty much a daily basis between valve jobs, boring and honing blocks etc. and my preference for a grinder is the Milwaukee 5192 for about $250 or so if you are on a budget and don't want to spend a ton of $$$. There is the more powerful Milwaukee grinder but it is about $100 more and weighs a bit more - believe me your arms will ache after a while. I get all my other supplies from Cylinder Head Abraisives out of Sacramento, CA 800-456-5474. A double cut oval shape burr like #SE5 does a great job of removing tons of metal fast. A single cut SE4 is good for smaller radii like around valve guides and the single cut leaves fewer 'scars'. I use the Pink stones PS186X for cleaning up the port of grinder marks then finish with a 60 grit cartridge roll on the intake and an 80 grit on exhaust. Not giving away my secrets for making aluminum heads look so good though...
Those would be what I consider the minimum essentioals for a starting porter. Of course my first set of heads was done with a Dremel, ugh. Not recommended as it takes about five times longer.
Tip on the grinder - cast iron doesn't cut well with the grinder moving 18,000rpm so I built a variable speed switch using a HD dimmer switch from Home Depot wired to it's own outlet and I can change speeds depending on what metal and burr I am using.
