2 of the 10 Head Studs are too long in ARPs Kit #208-4301 for my D16Z,and it aint the block cause i tried them on 2 other D blocks.The problem bolts are the one just next to the vtec solenoid on rear side(oil filter side) of cylinder #4,it bottoms out about an 1/2" sooner than the other 9 holes and the other is the rear one next to the cam gear on cylinder #1,the Cylinder Head steps down about 1/4" lower where the head stud pokes thru as compare to the other stud holes,ive contacted ARP about this,talked to two seperate guys,who both gave me the same line,that say i should tap and clean the treads and that they sold a thousand of these kits and never had such a problem...BS...they probably had no one complain cause they stacked washers to make them work,which is what ill have to do until ARP sees the light and makes a fix..anyway,,my point is,,dont buy ARP head stud kit #208-4301 for a D16Z or D16Y cause of poor fitting and you should not have to stack washers with it which both ARP tech guys said they dont recommend stacking washers like that!

 

i had the same problem. wasn't a big deal. just have 2 a little longer than the others.

 

well, for my money,i want it right,the kit would be perfect if it came with two studs shorter,one 1/2" shorter the other 1/4" shorter

 

i dont know what to tell ya. i cleaned all my holes first, so i know the were bottoming out.

 

The studs are suppose to be higher in those 2 locations. When you put the head on, you'll know why. Paul

 

I had that problem, except every one of the studs were too long.

I sent them back and got a full refund!
