427 Build
I am in the process of building a 427 stroker and have a question about heads. I have listed the specs that I have acquired thus far with regards to the build below:
427 Darton Sleeved LS1
12.5 comp
4:00 crank
256/264 - 625/625 - 113+4 hydraulic cam
FAST 90
Holley 90 TB
4:125 Dome Pistons
6:125 rods
I want to go with a set of CNC Ported Dart Heads:
250cc intake port - 68cc chambers - 2.08/1.60 intake/exhaust.
My question are:
Is this head to big for this build
What size spring for this cam?
Should the spring be a beehive or dual spring?
Thanks guys!

I ran a set of those heads on my 402 with a 90/90 and a cam just a bit smaller then that, and it worked out great. May even want to conisder and ls3 or ls7 top end. Definately go with dual springs.
