I need an opinion...
I need some opinions or advice on Goodson's port reshaping kit (PRK-99) for heads. It's a two part epoxy that acts like a filler for reshaping the port or adding material to thin spots. I need to know if this works for aluminum as well. I have not seen a product like this before, and I emailed Goodson for some more specifics but they were not very informative. If anyone has used this product or has heard anything about it, I would appreciate some feedback. I'm not advertising, I just need to know if this stuff really works. They say it can be sanded, drilled, tapped, and machined.
