349 CI on the cheap

What are your thoughts on degreeing the cam?
I have a Purple Shaft Cam
Adv. Duration: .268°/272°
Dur. @ .050'': 228°/231°
Lift: .450''/.455''
Centerline: 110°
Basic RPM: 1500-5800 RPM
I will redo a set of heads in the future, 302 castings if I can find them.
How much carb can I use for street/ strip...this is in a 2700 lb car
I am learning so any and all info gets written down. If I remember when I bought my short block it was .30 over with 4 valve relief pistons. How much is too much when milling 318 heads, are there any castings that are as good as the 302's if I can't find them. When I pull my motor for freshening I will go through it and have the block gone over, prepped for the 360 crank. Looking forward to looking stock and clean clock......Thanks for all the info..
