Possibly if Chevy made a 300.
Yes they will, but 305 heads have a smaller combustion chamber so it may raise your compression ratio.
The headers for a 350 and 305 are the same.
Yes, and well.
the block & heads are the same you just have to pull the 305 out & put the 350 back in
305 heads of course, 350 heads will fit for sure and possibly 400. obviously no big block heads will fit. a 305 with 400 heads gets you a little over 352. 350 with 400 heads is a 383. add and divide
No. The bore size is different between a 305 and 350. The 350 bore size is larger.
In the cylinder heads.
take them to a machine shop
no I respectfully disagree. I am running 305 Chevy TBI heads on my 1971 Chevy 307 and all is very well.
Higher compression ration which can increase hp. I installed 49cc heads on my 305 instead of the 64cc and got a higher compression ration and a fair amount of hp gain.
You will need to have the heads for the 305 bored out to the same size as the 350. I disagree: you can use the 305 heads on the 350 block but you will increase compression as the 305 heads have a smaller combustion chamber. The critical dimension is valve clearance. If compression ratio is a critical consideration, different pistons may be available which will bring the combustion chamber back to size. the 305 is from the 3.671 inch bore family. The 350 is from the 4.00 inch bore family. All small block heads have the same bolt pattern.
To remove the heads on a 305 Chevy, first disconnect the battery, carb and throttle cables. Also disconnect the sensors and vacuum hoses. Unplug water temp gauge sensor on the thermostat and disconnect pump from brackets.
