What happens if you put 350 heads on a 305?
Virtually any 350 heads will work on a 305. The high compression 350 heads are similiar in combustion chamber size & intake valve size to the 305 heads & will give a 305 the same performance as if using 305 heads.
Can you put 350 Vortec heads on a 305?
There’s both 350 and 305 vortecs. Heads from both these engines would physically bolt on to a 305, but bolting a set of 350 heads onto a 305 would hurt performance more than anything. The heads off a 305 vortec are actually pretty decent heads for a 305, and if you’re set on vortec heads, those are the ones you want.

How much horsepower can a 305 make?
So a 305 up against a 350 (even at the same horsepower) will always lose to the larger engine because the 350 will make more torque. I completely agree that a 305 can be built to make 450 hp.
How can I get more power out of my 305?
Are 305 and 350 pistons the same?
The 350 crank with a 305 rod-piston is not a problem. No balancing required for a stock piston or cast replacement. The 305 crank is the nastiest piece of junk that is associated with Small Blocks IMHO. 305-350 cast cranks were the same casting number and the only difference was the factory balancing.
Can you put Chevy 350 heads on backwards?

How do I know if my Chevy has a double hump head?
These heads got their nickname because of the raised identification shape on the each end. It’s two half-ovals connected by a straight bar-most easily described as “two humps.” Some of these are also nicknamed “Fuelie” heads because a version appeared on fuel-injected 327-powered Chevy Corvettes.
