Thoughts on build balancing

I‘m building a D4 code 351W, stock bore with D5AE-CA heads that are getting rebuilt. I plan on putting an Edelbrock 2181 Performer intake manifold, a 2182 cam, and a 1406 carb. Anybody have any experience with this combination? Any advice? TIA

Why D5 heads? Are you planning on flat top pistons to raise compression?

P.S. I found one source that states those heads have 58cc chambers, is that what you have?

Yep they‘re the 58cc chamber heads

Are you doing anything to the heads beside the rebuild? Porting?

Overall that is a solid combo, it won't make big HP but should be very torquey.

No I won’t be porting, the heads anyway. The machine shop won’t since they’re cast and said they’d take forever. I’m gonna run stock springs, but I don’t know what pushrod length to go with, the motor didn’t come with any. I was thinking about running Comp Cam kit RP-1436-16, and it includes the High Energy 8.152” length 5/16” diameter pushrods. Do I need to measure or would these be sufficient?
