Bought a used motor with these cases, what do you all think about the porting and epoxy work? I am unschooled and don't know if these are trash or treasure or somewhere in between.

This is part finished , see my epoxy work is a lot smoother transitions

I just stumbled across this today http://www.x-h2o.com/index.php?threads/home-porting.1540/ It has a lot of great info. From what I see keith, you are going to have a really nice set-up there when done. Matt_E I think suggested in that thread, that adding a slight upward pitch to the epoxied finger portion will help send the fuel charge upward a little faster for more responsive airflow transitioning. I can't help but wonder how much it would take away from crank lubrication though. There was one guy that asked about trenching the center of the epoxy region to help keep the crank lubed and still offer some rapid over the crank air flow. I don't remember if he had a response to that but it does sound like a logical concept.
Midlake, from what I see, I would say your new find is either just a quick job and not fully finished, or just not really well done. But it doesn't look like the case is a write off. If anything it just seems to need some refinement to get it up to snuff.

No reason to disagree, but can you be more specific? Is it something that should be scrapped, or can it be re-worked?

Well, this is strictly personal opinion from my part and by no means validated through experience...but, that epoxy doesn't look to be very well set or mixed. Given how the two side ports look I would say he was in a rush to get the job done. I am a stickler for quality and would be digging that stuff out. You don't know how well the previous owner prepped the surfaces, given the quality of the port work and seemingly rushed job I would be afraid to run that as it is. I have always liked knowing that the work put into it was done well and by my own time. That way there are no questions.
Well said by pro-pulsion above. The lack of attention to detail makes me question quality of prep work and mixing ratio,etc. Worry that it will come loose.
You can grind it out, reprep, and re epoxy them.

The porting does not look even on both sides and its very minor porting even though its difficult to tell from the photos but make sure you remove and replace the epoxy it looks sketcky..

What do you all think about the fingers being filled?

What is the benefit of filling the fingers verses not ? And is this a noticeable improvement for ported engines

my 62t had ramps that were coming loose. I just peeled em out and im gonna leave em out. shouldn't notice a difference at all when in the water. From what I understand the more reputable builders such as judge will install screws from the bottom into the fingers so the epoxy will have something to grab onto. good concept.

I would like to see the intake ports from the other side.

Epoxy will not come out if you prepare the area correctly
The only time i have seen it come out is when the engine was left sitting with salt water in it and its corroded and lifted the epoxy

I want to revive this thread a little bit with a few questions regarding the finger section of the intake tracts. Has anyone ever tried just grinding out the fingers instead of epoxy filling them? I was looking at various photos and now am wondering if it would be better to have the intake tracts opened larger by removing the fingers rather than smaller by filling them. I can appreciate that grinding is going to take a lot longer, but it is at least a guarantee that the epoxy will not have separation issues if the surfaces were not prepped well enough. I have read that filling the fingers and ramping the end up slightly helps improve the top range of the powerband, where as leaving the fingers untouched will benefit the the lower side through the mid range. Would it sound logical and hold some truth to assume that if the fingers were removed, it would open the intake tract up increasing signal strength through volume increases making the reeds act as a more efficient large venturi further speeding up the airflow?
