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.
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.
Possibly if Chevy made a 300.
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.
take them to a machine shop
In the cylinder heads.
no I respectfully disagree. I am running 305 Chevy TBI heads on my 1971 Chevy 307 and all is very well.
Yes, they will work. but you wont gain power because the little 305 isn't putting out enough flow to keep up with the heads
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.
