Instant Bolt On Horsepower. What LS3 Cylinder head upgrades will work for you?
20th Aug 2017
With the ever increasing popularity of Forced Induction horsepower is becoming easier to achieve and 1/4 mile ET's are rapidly decreasing.
When it comes to serious horsepower turbo engines one pain point seems to be lifting the cylinder heads under boost.
We frequently receive calls from customers looking for a stronger alternative to the LS3 Cylinder head to help prevent this. However this can be where it becomes an expensive exercise. Some Aftermarket Cylinder Heads require expensive aftermarket Rockers, Valves etc that may be out of your budget.
We have listed x3 of our most popular upgrades from the LS3 Heads that we have tried and tested for great results.
