Rick- you posted this question at the perfect time for me. As you know my dad bought the Holley Systemax II kit about 2 months ago for his car. Well it has taken to now to get funds to complete the install, and when we checked the manual to see what RR's it called for, it has the part number for the FMS 1.6 PEDESTAL mount units listed, but his heads have studs in them. So I called Holley and after several hours someone called me back from their carb. division. He said he knew nothing of the kit, but I had him look up our part number of the kit to tell me what heads came with it- guess what, it is the 300-575 2.02" stud mount head! I told that the 2.02 valve wouldn't work with the stock pistons, so he said I'd have to call back yesterday. So I called and the tech guy told me that with their cam the 2.02" head will fit factory pistons?!?!? I'm really confused now, but I see the recess your talking about. I wasn't that thrilled with these heads when I looked inside the intake ports where the rocker stud came down through- there was a hunk of aluminum just hanging by a thread there where they had tapped the hole, as soon as I toughed it it fell off. The thing was the size of my finger nail, just think what might have happened if it had broken off and gone into the motor!!! I still don't know what to do with these heads, as I'd hate to tear the car apart, put the head on and then find out it won't work and then have to send them back and wait for a new set. Plus I think the 2.02" valve would be overkill on his motor, I think it would kill velocity and therefore low end torque. Anyone else think this. Anyone have a recommendation as to what to do, keep the head, send it back, what?
