just put my 408 all together and took it up to the dyno, they said that i have an antifreeze leak out of the head. i am running MLS 4.100". they said it looked like it was comin from the head bolt possiby??? i have ARP studs in them

 

what heads? apparently there are some that would leak there. if they had a battery looking emblem on the head that you could see when you take off the valve cover then that's the bad heads. I'll post a link to my thread.

 

they are patriot stage 2's... apparently the one hand that works along side of the tuner on the dyno said that it looks almost as if the antifreeze is coming out the actual stud on the front corner of the #2 cylinder. is that possible?

 

My patriots push coolant fromt the from the #2 header bolt. I just put locktite and it holds really good. I think they were overported on that spot.
