440 Head gaskets and others

[TheCouzin]

Looking for advice on head Gaskets, valley pan gasket, intake gasket. I have Moroso (93055) valve cover gaskets already. Going to be getting rid of the K&N Air cleaner and finding a 440 one.

Need more info like why are you changing head gaskets, and what was in there previously

Changing them cause I just aquired this car. Its been sitting for a while from previous owner, and is leaking from head gaskets slightly. And just to give it a good once over since its winter here now. Also going to be changing fuel pump gasket too cause its leaking but thats pretty straight forward.

I havent pulled the heads yet to see what they got on it now.

Need tear it down and see what the piston stick out is, measure piston to valve clearance. A typical FelPro .040 type head gasket should be fine but there might be some reason a thicker one might be needed. Or maybe a thinner and add some compression.

Ok. Awesome. Sounds like I am trying to get ahead of myself. Ill pull the thing apart and see whats on there and take some measurments. Cheers

You will also need to figure out why the head gasket was leaking. Block could need decked or maybe a head is warped etc...

How does it run, drive and sound with that cam? I built a similar 440 with that cam, 440 Source heads, 10:1 JE pistons, etc. but I don't have the car done yet. Did he supply you with the dyno sheets? That horsepower number is a lot higher than I was figuring with that cam.

As mentioned previously: take the heads off and see what you have before you order parts.

Should be a fun torque monster for a street car.

………and is leaking from head gaskets slightly.

Leaking what?

Maybe post the cam specs so everyone doesn’t have to look it up.

Let me help since I just so happen to have the specs in front of me.
