?? RHS or edelbrock heads for my 408 ??

I'd run ported Edelbrock heads on the stroker. I have them on my current 360 @ 11-1 and it runs fine on 93 octane. Cam is 250* @ 050 duration which helps bleed off pressure at a low RPM.

The W2 comment is also a good idea. Valve train could be pricey. If you all ready have a hardened chrome shaft & roller rockers, purchase 8 off-set rockers.
