Tony;

1) For a street motor and even mild "race" motor the stock crank is fine.... Have it checked out and reground if necessary....

2) Forged flattop pistons with 4 reliefs or 4 eyebrows are a good choice,can't go wrong with forged pistons....

3) I'm using stock rods with ARP rod bolts that have been resized,I also polished and balanced the rods,not hard to do,but added insurance against failures,again for a 6,000rpm street engine they will work just fine.. Mine have for the last 17,000 miles with four or five trips to the 1/4 mile a year...

4) I would go with the AFR heads as they are CNC'd from the factory,need no work,just bolt them on,for the money I think they are the best heads on the market right now...

5)They come with 2.02 and 1.60 valves....

For a street motor that will be very streetable 400 hp will be fairly easy to reach with these parts and an Edlebrock Dual plane Performer RPM intake with a Holley 600 cfm carb and a cam with the lift around .500 and duration around 270 to 285... It will have a lot of low end "grunt" and still pull good thru 6,000 rpms....

My 351-W has flat top pistons,stock rods,C-9 iron heads that have been polished and ported and it should make around 350 hp at the flywheel with a 484 lift cam. Idles at 800rpms with 17 inches of vacum and putts around town if forth gear at 25 mph with no hesitation or spitting. Very easy to drive and gets decent gas mileage to boot....

Just my opinion.....
