Previously Asked Questions

When should I replace a cylinder head?
Look for signs of overheating. Fuse plugs for the 71 inline series will melt at 257 degrees Fahrenheit (125 degrees Celsius.) If these plugs are melted, or you otherwise suspect overheating had occurred, the cylinder head should be inspected for warping.

How do I know if the cylinder head had warped?
Using a feeler gauge and a straight-edge, check the warping along the long side (longitudinal) as well as width, or the shorter side (also called the transverse side.) The maximum warpage for 3-71 is .055 inches. For a 4-71, the maximum warpage is .008, and for a 6-71, the maximum warpage is .01 inches. For the transverse measurements (the width or shorter measurement) should not exceed .004 in the 3-71, 4-71 and 6-71. If you do not have a feeler gauge, click on your engine above and you will see the feeler gauge tool.

Do you offer rebuilt cylinder heads? Which would be better to buy?
All of our rebuilt engines are guaranteed and thoroughly inspected. Our new heads are inexpensive, and usually only slightly more than a rebuilt unit, so either way, you can get a new or like-new product for the price of used parts elsewhere.

Can I use the same Gasket Kit for the Two Valve 71 and Four Valve 71 Engines?
No, they are custom made for each engine. Our kits come complete with gaskets, valves, and seals, so simply click on your engine and you will get a kit that is ready for your project. This is STRONGLY recommended if you are replacing the cylinder head.

Is the Plug Kit required?
If you are replacing a cylinder head for the 4-71 Four Valve Engine (as well as all 6-71 and all 8-71 cylinder heads) it is ABSOULTELY needed.
