Re: L35 questions - now with pics
These are the L35s that Myclone so graciously hand ported for me...
This is the bowl and seat area after light blending and a once over polish.
Note the radius work left around the base of the bowl near the valve seal.
If you remove too much of that "Swirl" you will be causing more turbulence than increase in flow.
Opened up the backside all the way through the exhaust port.
We used a set of fel-pro copper gaskets to port match and then I made a stencil from the head and port matched my stock exhaust manifolds.
Intake ports he removed the casting and just rounded out the far corners.
Ports opened to match GM lower intake gaskets.
Chamber smoothed and polished.
It's not recommended to tamper with the area directly around the plug much unless you want to create hot spots.
These have screw in studs. the stockers have the shoulder.
No shoulder aftermarrket studs.
You will not fit a full bodied crane gold roller on that stud unless you have them drilled for the longer v8 studs and then they wont fit under the composite vortec valve covers without spacers.
So if you are set on 1.6's check out the roller tips. Summit actually has a nice set Jegs too.
Improvement over stock without a ton of machine work that would defeat the purpose of dealing with a budget head upgrade anyways.
