Porting the LIM (w/ pics)
Actually, what a was indicating doing with the template was not porting the heads. It was to get a template of the head ports so a guy could overlay the template on the LIM and see the head port size relative to the port on the LIM. Members are using various means of getting the LIM port shape/size to the size that gives maximum benefit, but there seems to be some confusion about the corner radius etc. I'm with you and do not endorse porting the heads unless you have some experience doing so.

I recall your pledxiglas CAI heatshild you made some time ago so I know you are pretty good with plexiglas...(among other things).

Awesome idea!
putertopia,
If you want me to do some kind of "trace" or "transfer" of the ports on the heads I have sitting on my bench, let me know.

I'm going to be tearing into the LIM/UIM probably this coming sunday. I'll go ahead and line it up to my heads, see how it looks. If I can save it, sweet. If not, I'll use the UIM that'* on there now.

Huh?
That actually went onto the new motor with the Throttle Body and the Matched Injectors

I think I'll be giving this a shot soon. I really like the idea of you guys (Wilwren and others with their LIM, TB and SC work) making all these little changes for small gains here and there. And it'* free! If there are gains to be made for free, you'd be stupid not to do it!

and you'd be more stupid to try it for the first time on your original parts. BUY SPARES.
Practice FIRST.
Oh yes, I already have a spare LIM to practice on. I don't trust my skill (or maybe my patience?) to do my heads. I'll be sending them out to the head shop we use at work. They've done impressive work for me before with my 300 HP 3100. The LIM I will try, though, but after the heads are done as I will want to match them.
