What is the thickness of head gasket?
Head Gasket should be . 030″ thick. Compression will be increased but no problem on iron heads. Compression will be in the 13:1 range using 3400 heads.
What happens if I use a thicker head gasket?
Changing gasket thickness can be used to fine-tune compression….How does it affect performance?
| Thinner Head Gaskets | Thicker Head Gaskets |
|---|---|
| Better sealing, less likely to blow | Prone to failure, because it adds space between the head and block |
| Slightly raises compression ratio | Slightly lowers compression ratio |
What is the compressed thickness of a Felpro head gasket?
Compressed Thickness (in.): 0.041 in.
Are Felpro head gaskets any good?
Fel-Pro gaskets are one of those that really meet & exceed OEM specifications. In many cases, they’re substantially better than the OEM gaskets your vehicle came with.

Can a K Series engine have head gasket failure?
The K Series engine has gained itself a bad reputation for head gasket failure and not without some justification. However, this has become something of a vicious circle with gasket failure often being diagnosed simply because “Rovers have gasket failure”.
Is the head gasket fitted in a normal way?
The gasket is fitted in a normal way and not only is made up of five separate layers, one main layer and two subordinate on top and two below, it has a different sealing arrangement so that there is no vulnerable sealing track to be displaced.
What was the weakness of the elastomer head gasket?
The main weakness of the original elastomer type gasket was that the rubber sealing beads would become crushed or displaced due to the effects of heat and the shuffling movement between head and block.
What causes a Peter Jones K Series engine to overheat?
The oil emulsifies and reduces the coolant efficiency, again resulting in overheating if left unnoticed. The K series heads must be resurfaced (skimmed) following headgasket failure as they not only warp, but the fire ring section is very narrow and etches into the head face, reducing the sealing effect and causing a further failure.
