Frequently Asked Questions
Do I really need to remove the cylinder heads to install these parts?
Yes, you have to pull the heads to swap the lifters. While the camshaft slides out from the front, the AFM lifters live deep in the engine valley. This is the perfect time to inspect your cylinder walls and valves for wear.
Will deleting AFM improve my gas mileage?
You should expect a slight drop in fuel economy. AFM exists primarily to help the manufacturer meet corporate average fuel economy standards during light cruising. By locking the engine into full-power mode, you are trading a few miles per gallon for consistent throttle response.
Can I reuse my old head bolts during this process?
Never reuse your original head bolts. These are torque-to-yield fasteners that stretch once they are tightened to their final specification. Using them a second time creates a high risk of head gasket leaks or bolt failure.
How much power can I realistically add with a delete cam?
A well-chosen cam usually adds 30 to 60 horsepower depending on the profile. Gains are more noticeable in the mid-to-high RPM range where the engine finally gets to breathe. Combine this with long-tube headers to see the best results.
Is it possible to perform this upgrade without a professional mechanic?
You can certainly manage this if you have a solid grasp of automotive mechanics and a torque wrench. It is a time-consuming project that requires patience and organization to track every bolt. If you are uncertain about timing chain alignment, reach out to a professional to avoid internal damage.
