I hope that there is someone that can give me some advice on the Edelbrock 6025 heads, I have a set and was planning on putting them on my 347, that is until I went to the edelbrock trailer at bradenton, I was told that I will have piston to valve clearance issues with these heads using a stock piston. Does anyone know anything about this? These are 2.02/ 1.60 heads using pedastal mount rockers. The pistons are Sealed Power flats with 4 valve reliefs. I am hoping for some sort of better news.. If not,, is there anyone interested in a set of new Performer Heads? Thanks to anyone that can lead me in the right direction.. You can email me at
