Will this work?

[CigarMan]

Building a 03 5.3 for my 72 LWB and want some opinions on this again, I want to make a nice DD with a little pep. I decided to stay EFI

Here is the plan, please jump in on anything I might have wrong.

Bought 243 heads, plan to port them.. Street port or CNC ? I am told street is just under valves. What components should I build this with? Rockers,rods,lifters?


Add comp cam, 54-408-11 seems to be the most recommended I see for what I want.

Have beehive springs? Keep or change?

Doug thorley long pipes seem to be a no brainier

X pipe

Have intake from Tahoe' wil this be ok or should I change?

I plan to locate coil packs behind intake and use competition gm valve covers and that slick ass plug wire rail I saw here

I ask here because, well you guys know and my friend who is a good mechanic on old school motors insist that I do what ever research is needed for this build. A reasonable request I know I just do not understand much so I have to ask...

Please ask Any questions you have, I only know what I want not how to get it

Thanks
