|bygddy||Got my guages in today, got a small compressor and die grinder, and the porting kit, plus an additional carbide cutting bit with a 6" shank to reach in deeper, will likely dissasemble the heads tommorow and take a run at this! Picked up an L88 hood this week for nothing, so that will get done in satin black and hopefully put on tommorow...grand total invested so far is right around 2000$ and I have everything to assemble the motor next week. This includes the purchase price of the car, various autometer guages, Hurst shifter, TCI shift kit, complete gasket set, headers, dynomax race bullits, Qjet Carb spacer, ....used parts include 416 heads, the quad I'm currently running, or a edelbrock 750 I had left over and a perfomer intake off my Malibu wagon....I'm really hoping I can get this into the 13's with this set up.....but that might be a tad optimistic.....any predictions? Other then the standard " it will blow up" sarcasm?|

I won't I won't lol......sand lightly, .....that's all....oh and Mr Gasket had a complete porting kit for 45$...!!! So that should be in tommorow...need a timing chain, plugs and wires, some thread sealer, and it should be ready to take apart, and reassemble next week!

DO NOT USE Roto discs to "resurface" anything. A sure way to **** up a flat machined surface.
Put those away. Use 80-120-180 on a long sanding block, bodymans file board.
to clean the matting faces if at all.
If they are not flat get them flat milled .005"

On a Pontiac I used thin stainless steel to block the crossover- never burned out.
On a Chevy head you can use furnace cement. Mine looked like below when done (the pitting is insignificant, the cement is into the crossover deep). From http://www.hotrodders.com/forum/chev...tml#post705525:

|vinniekq2||some intake gasket manufacturers include a cross over plug,use them.Its nice to find a flow bench and test the heads,do 1 port and retest to see if you are on the right direction.Also the guy with the bench can offer words of encouragement as well as direction. have fun,a little help is better than no help.With flow numbers you can better pick a camshaft|

I believe most intake gasket sets have the block off plates included. I haven't had any luck with them though as they burned right thru.

Electric die grinder and air die ginder*** Princess Auto. Give the Dremel to your wife.
( the bits sold at princess auto are not carbide, no good for porting cylinder heads ..)
Double cut carbide die grindering porting burr 's can be bought at many welding supply and industrial tool supply
stores. Not CTC. you want at least 1 with a long 5" 6" shaft to reach deep into the intake port to contour the valve guide boss shape.
Do a google search for David Vizard and cylinder heads. on amazon. buy the book(s).
" How to build max performance small blocks on a budget"
Read it, know it There will be a test.
You do not want to disable the vac advance. You want to retain it and adjust it to work correctly.
Get an adjustable vac adv.
Eastwood 6" carbide porting burr set
this is the one you must have to get dep in the port
"double cut" for cast iron,, single cut for aluminum.

kms tools and summit have a very good selection of abrasives.
What part of canada? There is a hobbyist head porter on the west coast that has a flow bench and does ok for a reasonable price.

Porting has always seemed rather daunting to me too, but if you want to try, a kit like these Standard Abrasives Kits would do it. Combine one of these kits with a die grinder and have at it. (Click on the pictures for the info)
