In a non roller cam block you can't use the stock roller lifters 5.0's use because they will protrude to far out of the lifter bores and oil the lifter valley which is what happens if you try and use a standard roller cam in that same block with standard roller lifters.....that's why you have to use a retro fit cam which is ground on a different base circle and you use the retro style lifters with link bars so they don't rotate on you........you can use a standard roller cam in a non roller block but the retro style lifters are like 500.00.....I almost choose that option when having my 347 built from ford strokers but the cost out weighted the benifit of a slightly stronger block for the power level I wanted....so I went with a standard roller block.....you can make anything work it's just not always cost effective

If you're wanting a cam that makes power up to around 6,000rpm but have that big of a carb and intake, you're just gonna lose power.

The small notches are required to remove/install the corner lifters w/out having to remove the heads, not a required modification to use them, more of a "ease for replacement w/out having to remove the heads" problem.... and not required if you use the linked lifters...... any other lifters will force you to use a reduced base circle HR cam. If you want to keep it flat tappet, and be 200% sure of choosing the best profile, you could check the cam evaluation/selection service at www.camshaftinnovations.com .....

Regarding the 700 cfm carb is way too big...... ..... it's not. I've used one for 15 yrs. in my 302 junk, and I had to increase jet sizes to get a good A/F there, no stumbling, no bogging, no hesitation, and accelerates like it should.... you need to tune it (or any other alternative anybody chooses) though. Besides...... wonder why Mr. Carroll Shelby used a 715 cfm Holley's in the GT350 289's .... or why I got better results from my old 289's with a 850 DP.... had a 600 cfm for daily driving, and the 850 was the "down to business" carb..... not because an 850 couldn't be used for a daily driver (which I did for a while anyway), but simply b/c it had a cracked/soldered base plate.

There is always going to be a debate on which intake to use on your engine. Everyone tends to favor what they have or have heard about that makes the BIGGEST HP! Personal application is really the question that should be asked. Now I know that I listed a Victor Jr. above but I also have a Performer RPM. I recently picked up the Victor Jr. because I found it at a swap meet for $50.
Single plane vs Dual plane is a debate that people need to be educated on. I'll just go ahead and post this link to help clear up anyone's debates.

It's an article that compares the 2 types of intakes and explains the differences as well. Worth reading!
