Edelbrock rpm heads for a small block

Why not just get a set of pro comps ?
They are made in Australia not China the rocker holes and exhaust holes are heli coiled .
Plus you can get them cnc ported cheap .
For the money I would go pro comp .
I have edelbrocks on a 340 and waiting for my cnc ported pro comps to arrive any day now.
Best of luck
Jim
