The Edelbrock Max Wedge victors are decent for the price, but not without some issues. The heads with valves from Edelbrock are setup for stock valve spring heights. If I used them again, I would get the heads without valves, then get longer valve. Because the longer valves will change the rocker geometry, mill off the rocker stands and use the maxwedge style rocker shaft hold downs.

On my 4.15" stroked 400 block (about 500"), with the KB/ICON flat top pistons it has about 12.4:1 compression. The pistons could use deeper valve pockets if you are going to run a cam with 270 or more duration @ 0.050.

I'm running a 264@0.050" cam and the engine makes over 650 HP.
