the ones on the lower outside row of the heads, by the exhaust / spark plugs.

Ok thats what I was thinking.

I called trick flow and they said that only the corner bolts need the sealant. has anyone done only the corner bolts and been ok?

Ok well here is what I did. I drained my the coolat and I went ahead and removed, and sealed one bolt at a time. I did this to all lower bolts and discovered that indeed ALL LOWER BOLTS GO THROUGH WATER PASSAGES. Im going to let the sealant cure overnight and i'll start her up tomorrow if i have time before work. thanks for your imput guys

do you guys think 24hours is enough for the sealant to set?

yes, as long as you did all five lower bolts on each side

Bump. If you are still a member, let me know the outcome after you did this. I've had coolant leaking from the rear lower passenger side head bolt for sometime, but the car runs good and no coolant in the oil.

Anyways, I'm changing the camshaft and debating whether I should pull the head off to fix the leakage issue or just reseal the one bolt because I did put thread sealer on all of them just that one bolt has issues.
