MONTE CARLO "COPO" Monte Carlo SS - Turbosaurus Build (Swinging Dick Racing's c*ck got bent... she bounced a little too high & hard, & came down awkwardly)

Did 8 of these today. I have about 20 hours in these heads thus far; at my billable rate I am not ahead of the game. But, the experience is what I am going for here.

I still have to clean the decks, lap the valves, and pull a few broken studs.

Seems like shimming the stock LS2/6 springs .060" isn't going to be worthwhile - especially if we dump this '01 LS1 cam (.470ish) for an '01 LS6 cam (.525").

This might just end up being a baby LS6. LOL.

Are you just using a cartridge roll to port ?

I have not actually touched these things with cartridge rolls. Just single and double-cut carbide burrs. The double cut burrs do a good job of blending.

Try a flame shaped burr. Then the cartridge rolls

That's what i use.

Here is what I have been using.

Try the fine flame those are to coarse for aluminum,

The flame is smooth and rounded no sharp boxy edges just like a fine booty!

Got a source for said flaming booty?

Cleaned the heads up (looks like one cylinder ate something it shouldn't have), pulled 3 busted bolts, cleaned and lapped the valves, put the 100K mile LS2/6 valve springs on (with new seals, retainers, and keepers - all left overs from the TSP heads on the wagon), and set them in place on ol' Quagmire over some stock MLS 4.8/5.3 gaskets. I am reusing the stock TTY bolts - cleaned the threads; and put ARP lube on the threads, under the heads, and on the shoulders as it makes torquing them smoother. Right now they are sitting at the initial torque spec until tomorrow(?).

EDIT: I meant to add that I broke all of the sharp edges with a smooth tooth file before sanding the decks with 220 grit and WD40 - it prevents the sandpaper from catching, and will save the head gaskets from being nicked if you lay the head down funny. I also took the edges off the combustion chambers with 220 grit - beats having hot spots.

With any luck this engine will end up in an '86 Camaro Natasha and I are going to look at in the morning; she wants to start racing again.
