I'm thinking about purchasing some SVE Performance Aluminum Cylinder Heads (79-95) #SVE-6049A-K since I will have the top end of the motor off next week. I'm going to be installing the SVE 5.0 Performance Intake Manifold Satin (86-95) #SVE-9424A along with SVE 70mm Throttle Body & EGR Spacer Polished (86-93) 5.0L #SVE-TB1501K and I already have the BBK Shorty Headers Chrome (79-93) 5.0L #BBK-1515 installed on the stock heads.
Questions: Will the hardware (rockers, bolts, pushrods) from my stock heads work on these heads or should I look into proper repl. parts? Seeing as how I'm already happy with the performance of the engine is a cam swap necessary? Should I upgrade the fuel injectors/system if I don't swap cams? If I'm running stock pistons and cam do I need to worry about intake/exhaust valves to piston clearance? I'm sure my current set up is not greater then .500 lift.
Your factory heads should be a pedestal mount rocker arm. The SVE aluminum heads are a stud mount so you will have to swap those out for sure. Head bolts and push-rods should be alright as well but double check the push-rod length to make sure. If you use a stock cam and pistons, you should not run into any piston to valve clearance issues. Your stock injectors will work fine on this combo as well.
