They are both crappy sets of heads, neither of which are worthy of a 351. Do a google search of them both and you will see all the negativity on them. I haven't seen the E streets up close, but know people with serious issues with them, but i have seen the patriots and they are a mess, you get what you pay for.
Cnc twisted wedges and afr 185's would be the best choices.
No point in killing yourself to make this 351 work just to get so so power.
You current plan sounds like you are going to drop quite a bit of money and the car really isn't going to be all the quick.
Don't think it doesn't happen, because it does, someone buys an old 351, slaps a bunch of mediocre parts on it, and now they have a car that's heavier and doesn't go much faster than a bolt on 302.
A purpose built from the ground up 351 based engine can be extremely fast, but one that isn't very well thought out can be very slow.
My advice would be to get a donor 5.0 car and take all the necessary parts to convert it to a efi v8, including all engine harness's, fuel lines, computer.
Piecing it together will take forever.
I bet you can get a parts car for $500 or less that comes without the trans or engine.
