3769973 318 Heads on my new motor

There is so much information about head casting numbers and opinions on what to do with them.

In a fresh 318 mild freshen up ( it's a 74 casting date ), are casting number 3769973 heads with 360 intake valves installed and the heads decked a bit to raise compression a decent way to go? I read somewhere that these heads have the hardened seats.:cheers:

I bought this motor carb to pan it has not be run yet though the workmanship is top notch. I'll post pics when I pick it up this weekend


As for the rest, it has a Hemi grind cam (dont know what brand yet). Lift is is measured around .480 with stock rockers. Probably a little lumpy idle right?

Carb is a Holley 80457 600cfm. Intake is an Edelbrock Performer.

I have a set of 340 manifolds I was going to use and gasket match port them...What size pipes should I get?

Should be fun to drive in a Duster with a 833 4 speed right?

The rear is stock 8 1/4 and the car left the factory with a 904 in it.
Didnt look at the tag on the pumpkin yet but wanted to know if this rear end gearing was going to be OK with an 833?

Any comments will be appreciated, Thanks
