Edelbrock heads.

IMO, a zero deck height piston and a closed chambered Edelbrock head with a good stout but still streetable cam is an excellent way to go. You can adjust the final compression ratio sum with head gasket thickness. The above suggestion I have run several times and I am building a 360 right now like this.

You can run a head gasket in the .035 (with good rods and bolts!) to .050 area with a cam in the 244* @.050 range. This is pump gas, 93.

My engine runs the .038 gasket and a 251* @ .050 cam.
On the wife's 360, it is a thicker gasket that looses the quench but the cam is small and gearing is 3.23. Huge room to grow.

If your going to run a dome and want to move away from stock iron heads, I suggest W2's well ported. The only 3 draw backs are heavy iron weight and expensive rocker arms & headers.
However, if your truly interested in making power, your going to pay a lot for headers anyway (TTI or Dougs) and the price difference in good rocker arms isnt horrible when you get to this level.
If your looking for upper 400 to 500+ hp, the above applies and cost differences are small between the gear.
