I am in the process of getting ready to swap cyl heads and I am tempted to port the exhaust and inlets. I have the 3.0 cams but kept the original bridge.

I have no probs refurbing the heads, I have done many before so I know how much of a difference that will make but unsure about the porting or whether i should do it having never done it before......

opinions please!

Go for it. Why not?

I port heads for a living, & am allways after bits!

Port it to match a 3.0 inlet divider

I have a good book on the subject if you fancy a go..

From what I have read it seems that porting the inlets is the most important, and that leaving a lip to the exhaust manifold is important to reduce back pressure. Is this accurate?
