Advice about a 360.

Yea, here's a few and think hard on them otherwise I'll call it going backwards!

Stay with the roller cam!
Use roller rockers!
The factor roller lifters are fine! Use them again and again and again!
Dump the F.I.
Do use a dual plane intake
Do use a quality distributor and ignition system
Do not use the one size fits all 1-5/8 header!

Check out Hugesengines.com for a cam & other parts for the engine.
Choose the cam based on your driving rpm range before you pick something to dang large and piss yourself off and throw wrenches around.

If your going to build it right and performance is in the game plan, look to a flat top piston @ a zero deck height. A KB-107 or the equal from Federal Mougal with the anti scuff coating are excellent choices for a 360!

Been there done that and in the middle of doing it again!
2 more 360 on a stand awaiting to go! Now I need cars! Lmao!
