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?

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"

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!

Yah, got all my gaskets today, there is a crossover restricter but it doesn't blokjck it completely....may find a piece of heavier guage tin, or the furnace stuff to plug it....as for porting, I borrowed a compressor, I have an air die grinder I can use, just need some cutting bits, i have little polishing brushes for my dremel and sanding bits as well, just need cutting bits for the die grinder, tryng to do this without spending a dime has been entertaining, heads are getting overnight flushed with clr to clean out the coolant passages, then brake clean, and tide, and a pressure washer, then a light roloc disk to "resurface" lol, then lap the valves, install springs and new seals and viola! Again, my soul intent here is to run down a buddies big dollar roller 355 in his regal using junk I had laying around, in a 750$ vette I pulled out of a feild....he bashes my sht all day...but his expensive junk is so mismatched it should be cake to beat him using the right combo of junk done smart....

cobalt327 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:

And when blocking off the heat passage on my intake can I simply use thin aluminum Ala: pop can? I figured I would just cut to the proper shape and use that spray gasket sticky stuff to hold it in place until its bolted down?

No pop can material. It will be gone quick.

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.

F-BIRD'88 Electric die grinder and air die ginder*** Princess Auto. Give the Dremel to your wife.
http://www.princessauto.com/pal/prod...ic-Die-Grinder

( 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
Amazon Amazon

this is the one you must have to get dep in the port

vinniekq2 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.

Any idea if that's something I can buy locally (Canadian) like, a home depot, or a lows sorta deal? And anyone have a basic tutorial on porting these heads?
Thanks
