I have a 86 GT and i want to put better heads on it but the pistons do not have valve reliefs in the pistons. According to what i have read i need to fly cut the pistons. Does anyone have any experience with this?
Yes and no. I never had valve reliefs cut in but instead went with the TFS heads. If you need a link let me know. Your'e restricted on lift and duration on the cam for an 86. I do know however, that you can get the pistons flycut without having to pull the motor out of the car. I've spoken with a few other 86ers that have had the pistons flycut. Most automotive machine shops should be able to hook you up.
