Ok, I'm trying to design my own top end now. I was pondering using vortec items on my 72 SBC 350. Is this possible? Do the late model heads bolt to the early model block? Sorry to make you guys read a book...

If i were to do it, i would want to use these heads:
SB Chevy Late Model Vortec Heads
• Available in Cast Iron or Aluminum
• 190cc Intake Runners
• 64cc Combustion Chambers
• 2.02"/1.60" valves
• Straight plug
• Vortec intake
bolt pattern
• Bare
• Sold as each $280.00

This intake:
Edelbrock Performer RPM Air-Gap (1500-6500)
• Dual-plane, low rise intake
manifold with Powerful
Air-Gap design
• Features an open air space
that separates the runners
from the hot engine oil
resulting in a cooler, denser charge for more power $216.00

This Carburator:
Holley Double Pumper Carbs
• Model 4150
• Mechanical secondaries
• Manual choke
• Dual feed fuel inlet
• Center hung floats
• Power valve blow-out protection
650 CFM $337.84 OR 700 CFM $362

This cam based on it's use description:
Comp Cam- Magnum Camshaft
Adv. Dur.: 292/292
Dur. @ .050: 244/244
Lobe Sep.: .501
Gross Lift: 110 $156.68 /w Lifters

Thank you for any help in advance, I'm really new at trying to make everything match. I also want to change my rods to these:
Renegade“Claimer” Series I-Beam
Connecting Rods
• Manufactured from 5140 steel
with polished beams
• Connecting rods are
within +/- 5 grams in a set
• ARP 8740 rod bolts included
• Quality inspected in the USA $154.44
They are 5.7" pressfit rods.

I want to change to Speed Pro, Hypereutetic pistons. Flat top, 4 reliefs, and 9.35 compression with 64 cc heads (the vortecs i listed are 64cc) $94.40/set

There's my book. Sorry!
