Sho intake/exhaust ports and head port pics
HEY GUYS.....since reading Jerry's thread on machining the intake manifold and running a bigger TB....I became very interested in the design of the intake and exhaust posrts....both on the head and the (intake/exhaust) manifolds.
The good news is this.....they're pretty damn sweet from the factory....after taking some pics and running my fingers down the ports...there's no BLATANTLY OBVIOUS AREAS THAT NEED TO BE ADDRESSED. About the only thing I saw that maybe I would like to do to mine is an Extrude-Hone on the exhaust manifold to clean up some very minor casting flash and some tiny ridges I felt. As I'm not an expert by any stretch of the imagination.... I'll let you guys decide for yourselves......
Here's the intake manifold runners, then the intake ports on the head...then the CC valve shot:

The next pics are of the exhaust port on the head, and the exhaust manifold runners:
See what you guys think.........and hold the Salt-Away jokes plz......

For those that want to clean up the intake a touch on the cheap (Extrude honing is not cheap) a dremel with the flexable extension does nicely, but don't get too carried away.

I cant see the exhaust side but there appears to be a large ridge around the back of the intake valve that could be cleaned up quite well.
Put some dye around the valves and seat them and see how much material is left around the vlave. I bet blending the area may help flow and velocity
Also bolt them all togather and see how well they mate up, it could be an area to look at as well.
