Question 1

____________________ is a broad term that refers to parts that are sold by the non-OE market.

Accepted Answer

Aftermarket

Question 2

What are the steps involved in installing cylinder heads?

Accepted Answer

1. Be sure to install the cylinder head gaskets in the right direction. 
2. Most engines have dowels to align the heads. If there are no dowels, make alignment pilots by cutting the heads off two long bolts and hack-sawing screwdriver grooves in their tops. These aligning studs will help protect the head gasket from damage during installation and can be removed easily after the head is installed. 
3. Be sure to compare the head gasket to the head to see that it is the correct one. Check that the fire rings around the combustion chambers fit and that oil and coolant passageways line up.
