Okay, I just got done installing my new 331 with AFR 185 heads. I fired it up yesterday and it was kind of running like crap...a few clacking sounds here and there from what sounded like rocker noise. Anyways, yesterday, after it ran for a little bit, I noticed some antifreeze around the lower headbolt on the #5 cylinder, which is the front cylinder on the driver's side. Today, I fired it up and I don't hear any clacking and it runs smoother, but the antifreeze is still seeping out slowly from that bolt...what is the problem? That is the only bolt that has that problem...help!

The lower head bolts go into the water jackets so you have to put thread sealer on them. I used arp thread sealer on mine and no leaks.

Okay, thanks alot....I guess that I will have to wait until monday to order some thread sealer. As for now, I have to figure out my intermitent "knock" problem that comes from the motor. It kind of sounds like a rocker hititng the cover, but it shouldn't be. Oh well, I'll have my neighbor look at it...I'm sure he'll know. josh
