351w roller vs 351 non-roller blocks

[Pman1961]

Blykins, thank you very much for the information. I've been a Chevy man all my life so I'm needing a little education on Fords. With the deck height being slightly different 9.48" for 69 and 70 years over 9.5" have you heard of any instances of head or intake needing milling to compensate the differences? When you say 'massage the pan' will it need a bump or two to clear or something more like removal of metal and rebuild? Could the girdle be ground slightly? My car is SPF 2423 and I currently have the 351w 385hp crate motor with 2k miles. Runs great and has excellent mannerizms but I'm wanting a bit more since I'm a hot rodder at heart. Not to abuse the car it's that feeling you get driving the car when you know it can get nasty when asked. I had considered stroking my Sportsman block but in the past having machine work done took very very long time and we are getting into the good weather so I would like to keep my down time to a minimum. So my options are to swap my existing components onto the new block and part out the 385hp crate motor or sell my motor as a whole and build a new motor. I'm going to be using the Keith Craft 195cc Signature heads on the 408 combo. Anybody want a perfectly running motor?
