Aluminum cylinder heads

It’s not a race car, just looking for a little more performance and plug clearance.
No. You don't need the Trick Flows at all. Waste of money on a mild engine. And never mind all the questions about gearing and converter stall speeds, 0-60 or a long synopsis on how to hook a car or any of that. It's irrelevant to your situation.The Edelbrock E Streets are the head you need and will work just fine for your application.As Andy stated above just double check your compression with the 75cc chambers. If you want decent pricing and someone who can set your E Streets up for your particular application call and talk to Todd at Marsh performance.
