305 Performance Heads

If you’re looking for performance heads for your 305, there are a few things to keep in mind. First off, what kind of performance are you looking for? Are you trying to increase horsepower, torque, or both?

And secondly, what kind of budget do you have to work with? There are a few different types of heads available for the 305, so it’s important to select the right one for your needs. If you’re just looking for a small boost in power, then stock replacement heads may be all you need.

But if you’re after more serious gains, then aftermarket performance heads are the way to go. When shopping for performance heads, it’s important to pay attention to the flow rates. The higher the flow rate, the more air and fuel the engine can take in and therefore the more power it can produce.

It really depends on your goals and budget. But if you’re after maximum power gains, then aftermarket heads with high flow rates and large valves are going to be your best bet.
