I need to deep port match the runners on a edelbrock performer 318/360 Intake to match the larger ports on my heads
How deep is deep and what tooling would you recommend ?
I used to care but....... things have changed

You can buy 6" long rotary bits for cutting alum or steel.. I also have 12" long arbor when using tooste rolls for porting... all are used with either a air or electric.. I use both a lot of times... all 1/4" shanks

When doing aluminum, be careful about loading up the bits and not cleaning them out with a scribe. I have a 5K rpm air drill that I use for most roughing in with the carbide cutters, I found that the 20K die grinders took off too much material too fast, and they liked to bounce around too much. A little slower = a little more control. The die grinders work good with the sanding rolls though. Tim

Keep dipping the cutter in WD-40 will really help keep the aluminum from building up in the flutes.

Awhile back there was a comprehensive thread here on the different types/uses for porting burrs (for faster work/longer life). If my printer was up I wanted to print it out.

Have a good port matched gasket to the heads and make sure the bolt holes line up well.. then transfer that to the intake.. blend it in as far as possible

All the good aluminum cutters have a lot bigger cutter edges on them and are further a lot further apart than the one shown in that picture. Those type are for steel, iron and other harder metals than aluminum As far as keeping the aluminum from sticking to the bits using candle wax or parafin to coat them frequently helps a lot I roll the bit in it by hand before starting and again as needed

I rarely use the wider aluminum burrs either. I use a mixture of WD40 and transmission fluid and port at a slower speed than a lot of guys do as I do it for recreation and not money. My Foredom grinder has a foot pedal to control the speed and with using the finer tooth (cast iron burrs) I usually don't even need a sanding roll job after I am finished.

John you turned me on to the idea of the $20 router speed control from HF for my electric. works like a champ! Able to control the bounce and the aggressiveness with the speed.
It may be ugly, but it sure is slow.

I'll look into that once it's warm enough to get back to the shop! Cutter bounce is nothing compared to shivering.
