From left to right...
Throttle body-to-plastic upper intake gasket...The green one appears to be the EGR pipe in the upper plastic intake O-ring...The last one is the thermostat oring...
On the quality of the heads i bought from J & C... I have used their heads on probably a half dozen Ford v6 products over the last 4 years and I also have a set of their aluminum heads on a stroker V8 I installed in my old Ranger...I have used their products on other peoples' engines and never had a problem with them...
I knew the differences in the 95TM vs 98TM heads were primarily in the exhaust ports and what I did was to blend the exhaust ports to match the openings in the exhaust manifolds...I wanted no sharp edges and no restrictions to exhaust out of the heads...When you pull the exhaust manifolds off look at the port area in the exhaust manifold vs the port area in the head...I also knew that I would be changing the exhaust piping to better flow throughout the system and should also increase and maintain exhaust velocity by reducing the non mandrel bends, adding high flow cats throughout the system, adding a dual in/dual out muffler and maintaining the same pipe diameter throughout the exhaust system...My exhaust system has a number of crimped bends, multiple orifice diameters and cat convertors that had 170k on them...
Look at the pics to see what the head port vs exhaust port mismatch was on the old engine...See the darker blocked areas on the face of the exhaust manifold? That is port blockage by the manifold itself...The port was actually bigger than the manifold opening was...But not anymore... I opened the manifold face to match the gaskets and the head ports...You will see that the manifold gaskets are designed to fit the port in the head not necessarily the ports in the manifold...I matched the exhaust ports to the manifold gasket and the intake manifold to the intake gasket as well...There is not as much of a difference in the intake face to head interface as the exhaust side though...
Just put a gasket on either exhaust or intake manifolds and you will see the difference...
These are the ones I'm not sure about in the Fel Pro Gasket Set. I think the round black one to the right is the thermostat housing gasket, but not sure.
Anyone know which is which?
