400 heads

[frogman73]

I want to put some good aftermarket heads on my 400 block. any suggestions or ideas out there

[John_Kunkel]

Just about all of the aftermarket heads are "good" but, if your 400 still has the stock compression, I'd look for the smallest combustion chamber you can find.

You said 400 block. Are you building something or do you have an engine already together?

Thats what my car has in it now .

What are your immediate goals and long term goals?

[BSB67]

Get some Stealths.  Cut 0.060" and intake surface to match.  Back cut the valves, and put a good comp valve grind on them,  use a 0.027 head gasket.  If you have adjustable valve train, put a small solid cam in.

And then add a nice stroker kit.    (hey, why not?)

Thats what im wanting to add a stocker kit it looks like 440.com have some nice kits.

What are your immediate goals and long term goals?

Again, what are your immediate and long term goals. There are many good aftermarket aluminum heads and they have different areas where they are most appropriate. Street, race, economy, power, looks, budget?

1973 400....Pistons too far in the hole. Heads? Open Chamber....Low Compression= Low HP....Time to rebuild with far better parts. Stealth heads, Mild Hyd. cam, Headers, 700 DP Holley in a Performer RPM Intake, MSD ignition...A Stroker kit would work wonders as well.

Thanks I just need a idea what to start with
