Slingshot Ported Heads

ZZP is now releasing ported heads for the Slingshot! The direct link to the product can be found here https://zzperformance.com/coll…oducts/ecotec-ported-head I have cores in bound which should be here by the end of the week. The cores carry a refundable $100 core charge that you will get back once we get your old head back. Alternatively, you can send me your head and I will port that and send it back and you can circumvent the core charge process all together. This is a great mod for the NA and the turbo setups!

A ported head increases airflow by reducing restriction therefore more high rpm horsepower. Increasing head flow creates more horsepower at the same boost level and works very well with aftermarket cams. Each head comes fully assembled minus cams, rockers, and lash adjusters.

All head come with the following:

• Gasket match
• Polish and blend runners
• Blend Bowls
• Reground valves
• Reground valve seats
• 82# Valve Springs & Titanium Retainers (included)
• Fully assembled minus cams, rockers, and lash adjusters.

All flowed at 28", 3.5" bore plate, exh had a 1 5/8" flow tube, and stock valves (int. 35mm, exh. 30mm) Do NOT be fooled by other venders flowing heads without a flow tube, in the real world people run headers, not open heads without headers or manifolds attached.

(These numbers are an LSJ head, LE5 heads will flow very similar)

Core charge drop down:

This amount is refundable when you return your stock head. If your core head needs repairs, the core refund will be docked to cover the repair.

While you have the head off it would also be a great time to replace the non-reusable head bolts with a set of ARP reusable head studs. You can find them here https://zzperformance.com/coll…roducts/ecotec-head-studs You will also need a new head gasket for the head swap and you can find those here https://zzperformance.com/coll…roducts/le5-head-gasket-1 As always, if you have any questions, you can always email me directly at Kyle@zzperformace.com
