Stock long block with vortech

So blew up my 347, #1main bearing failed and the crank snapped(Scat cast) right in front of the #2 main

I may try to salvage what I can out of it but the stock block after a failure like that has me concerned.

So my plan for the rest of the season is to throw my stock long block(118k miles) in with the vortech(possibly pulley change for less boost)

What valve springs should I use on the E7 heads and will I need hardened push rods too? Most likely staying with stock rockers

Use the heads off of your 347!

How about stock heads with upgraded springs?

I would be keeping the stock cam in it...more concerned about the low seat pressure of the factory springs with boost..

Ok cool thank you. So valve spring and push rod upgrade is not a necessity.
