Default 1996 f250 351 into fox body

hey guys, new here but i have been doing some reading previous to my first post. i know there is a sticky for this swap but i had a few other questions. im not doing this build just yet but i want to start getting my ideas put together

i have a 302 in my car now with gt40 aluminum heads, ford x cam, bbk ssi intake manifold. i know the cam and the heads will work but the holes for the head bolts need to be opened up some.

i know the lower intake manifold will not fit do they make a kit to make this work or can i get a new lower to fit this engine and bolt up to my existing upper?

would my heads be worth reusing would they work well with this motor?

next this may be a dumb question but would a '96 351 be a roller motor?

and does any one know if the water pumps flow the same direction?

thanks for the help

you would be wise to sell off the BBK intake to someone else who doesn't know any better...

what intake manifold do you guys suggest for a street strip set up. i would like to try and get a good 400-450 hp setup. i may go with a 408 set up though not sure

GT40 heads don't flow for schit...
Useless for power on a 302 so on a 351, the point is moot.

Go with either AFR heads, TrickFlow twisted wedge or Edelbrock Victor JR.
They're all good pieces.
185cc would be a minimum on a 351 mill but for something over 450 horses you'll need 205cc and above, especially if you plan to go FI.

I'm building a 408 for my 70 Cougar at the moment and I will use AFR 205cc heads.
The 185s that are on my 347 right now won't do.
