I purchased a set of GT40 heads off of ebay recently. I got a pretty good deal on them, but when I recieved them, I am not sure how to tell if they are really GT40, or stock cobras? How can I tell the difference before I try to install them, in case I need to get my money back.
Thanks!
Take a pic of the ends of the heads and post it on here. You can look at the casting and if you see 3 vertical lines on the ends of the casting, and GT40 is in the casting near one of the springs.
