I am rebuilding a 351W and purchased the Eagle 408 stroker kit which included JE forged aluminum dished piston, h-beam connecting rods along with the rings and bearings (Clevite). Excellent kit. Due to the larger rotating assembly some notching of the cylinder heads was required. I also went with the AFR 205cc race ready heads and the Edelbrock Air-Gap which is a dual plane since I plan on running this on the street. I went with the CompCam Extreme Energy 282 hydraulic roller cam and a Holley 750cfm double pumper. It should be a good set up and the machine shop also agreed with my configuration.

When pricing your kit and heads make sure you know exactly what they contain because I have seen heads cheaper but not completely assembled. JD's Performance website has decent prices. Summit Racing is another good source and they can get all kinds of products usually very quickly.
