SBC Chevy GM Aluminum Cylinder Heads Bare 210cc 64cc

Small Block Chevy ProComp Aluminum Cylinder Heads

210cc Intake Port, 64cc Chamber, 2.02/1.6 Valve, Angle Plug 

   

 You are bidding on a new pair of ProComp Motorsports small block Chevy aluminum cylinder heads. These heads are bare and ready to assemble. Comes with features normally found in heads costing much more, including: 

• Hardened exhaust seats for unleaded fuel compatibility
• Bronze valve guides
• Manufactured with aircraft quality high grade aluminum alloy
• Multi-angle seat design for improved flow at low lifts
• Advanced port design for improved flow at all lifts
• Advanced combustion chamber design allows superb flame travel and burn
• Additional pushrod clearance machined along outside port walls
• Can use either early or late (Vortec) intakes
• Can use either perimeter bolt pattern or centerbolt valve covers
• Threaded accessory holes in ends of heads
• Retains stock 23 degree angle and intake/exhaust bolt locations
• Thick deck to resist warping and allow for additional milling if desired
• Does not require offset rocker arms

 These heads will work for all small blocks including 400s (no steam holes). Heads are drilled for both the earlier style intake bolt pattern (pre '87) that had all bolts going in at an angle and the newer Vortec style that has 4 on each side going straight down in.

* Please note intake port height. These are a raised runner design. Stock and some aftermarket intakes may not cover port, you will need to compare this to the intake you plan to run. We recommend either a Fel-Pro 1206 intake gasket when using early style intake types or our KMJ 1255 when using Vortec style intakes. Both may require slight trimming but are very close. The Fel-Pro 1405 is probably the best exhaust gasket choice although the 1404 would work also with minor trimming. See our ebay store for gaskets. Any of the above qualifies for free shipping when also ordered with these heads. Please request a combined invoice to receive discount. If you have any questions feel free to call us at (515)733-2890

 These heads are a great choice and at a great price. Perfect for high performance/race applications where a quality head at an affordable price is desired.

 210cc intake port works well out of the box on engines with around 500-600 projected HP. Further gains can be had with gasket matching and porting techniques. Works especially well for larger displacement and stroker engines such as 383 and 400 engines.

 Aluminum material allows the benefit of higher compression ratios on the street compared to iron heads, not to mention that it saves nearly 20 lbs per head verses the factory ones!

 You can also use standard off the shelf items such as pistons, rocker arms, guideplates, studs (accepts either 3/8" or 7/16"), and stud girdles.

Payment:   

Please make payment within 7 days of purchase.  Paypal and Visa/MC/Discover credit card payments are accepted.

CREDIT CARD PAYMENTS -  

We use our own merchant account to process credit card payments.  Using a third party source to route payment from your card to us, such as through Paypal, many times will not work.  You can call us at (515)733-2890 and we can take your payment and answer any questions you may have.  Just let the salesperson know it is payment for an ebay item and we will insure that it gets processed as quickly as possible.

PAYPAL PAYMENTS -

The majority of Paypal payments can be processed within 2-3 hours after received during our normal weekday business times.  To prevent any delays with your order you should watch for the following common issues:

• Be sure your shipping address has a physical address that Fedex/UPS can deliver to.  Addresses that only have a PO Box can cause long delays and almost always result with having to credit/cancel the order in the end.  You should be able to add one onto your payment when going through the payment process.
• Be sure the shipping address is correct when making payment.  Shipments will go to the address that comes through on the payment.  Within a short time it may be already shipped and on the way.
• Some of our listings may request a "note to seller" to let us know if you have a certain preference or need a specific thing such things as sizes, colors, etc.  Putting a note on your Paypal payment is the best way to insure it should not be missed.
• In order to comply with Paypal's buyer/seller protection policy, any (single) payment having a total of $250 or more must be sent with signature confirmation on delivery.  This applies to all packages that may be associated with the payment.  If the order requires multiple packages someone will need to sign for each one.

If you find there there is any problem with your payment or order we recommend calling us during normal business hours if at all possible.  If you miss us during regular hours you can leave a voicemail message on our phone system.  While we do our best to keep up with ebay messages, during times of heavy volume an order can get processed and shipped before we're able to get through them all to stop or change an order.
