Copper head gasket on Gen 6 454
I have a Gen VI 454 +.030" that I'm building. I had the block decked .010" and the heads are razor straight. Does anyone see any issues with running an SCE Pro copper head gasket? They're supposed to be for O ring heads. Mine aren't, but my understanding is that I can use the copper spray and they'll seal fine with flat heads/block. The reason I want to use them is to tailor my compression and quench. Standard gaskets didn't get me where I want to be. With the copper gaskets, I'll be at 9.75:1 and .046". Price is right also at $100.50/pair. I think that will wind up perfect with my roller cam. .241/.249 @ .050 and .625/.625.

I think Grady has copper gaskets on his L88 (in his sweet red lil '67)

Nothin' like a freshly painted BBC! What kind of numbers are you looking for?

I ran my specs through a desktop dyno and came up with this. If I'm anywhere near it, I'll be happy. She's not a race car.

Some nice flat torque from 2-5. Plenty of HP to have some fun!!!

Man, that's killer. For what I want to do with my old Camaro, a big block would probably be the better (and cheaper) route, but I'd hate to lose the tunnel ram. I could always do a BB with a high rise manifold, carb spacer and put a blower scoop on it. That combo would probably stick out the hood some.

No reason you can't still run a tunnel ram. There's a bbc tunnel ram local on Craigslist with two 600 Holleys for $1,200. |

We are doing a TR on Benjamin's Nova with a rather mild cam, and are running two 600CFM Holleys that Eric Jackson set up for us - should be good to go.
