hi there all 305's have hydralic valves but they still can be adjusted to remove valve noise and lash hope the clears up your question nate
The exhast valves are larger.
yes
In the cylinder heads.
1. Pass., side, on the intake, below the carb.
The intakes are always bigger than the exhausts.
That's what the gas pedal does.
Yes it will. It will bolt right on... 100% interchangeable.
it is a knock sensor that is used to adjust the ignition timing.
It could be done with high compression, big valves, and a roller cam, or a supercharger, or nitrous oxide.
yes it will bolt right in and all accessories will work but unless you change your carb or have someone adjust for the proper mixture for the bigger motor it wont give you its full potential but its a very easy swap
Yes they both have 4 inch bores but if the chamber size where the valves is different it will change the compression.
It is bolted to the rear main cap and inside of the oil pan.
