BB Head swap

I just got the 396 running last week after two long years of waiting. It's pretty much a stock motor with closed chambered heads. The problem I'm having is a slight amount of foam and bubbles in the top of the radiator. This really concerns me like maybe a cracked head? I had the heads rebuilt a few years ago and was told they pressure checked fine. Is this the best way to check heads or should they have been magnifluxed? Needless to say the place that did my heads is long gone. I was also wondering if I were to convert to open chambered heads would I have to change the pistons? I've been told that todays fuel Is'nt high octane enough for my current set up and I may have to change them out anyway. Any help on this would be greatly appreciated. Thank You all very much.

Re: BB Head swap

Open chamber heads and closed chamber pistons is OK. -Just not the other way around.. This will lower your compression ratio considerably..

The easiest fix is "Chemiweld" or "Irontite"! The stuff that seals up cracks in engines.. If you're going to swap heads, who cares? Just get it running so you can enjoy it until you do the head swap.

Bubbles in your coolant sound like either a blown head gasket or a crack in your combustion chamber. Get a mechanic to check if those bubbles are exhaust with a sniffer.. A good mechanic should have one.

Thumbs up Re: BB Head swap

Please consider retorquing them first to at least check to see if they haven't reset themselves??

Otherwise, you can drain her, flush her 100 percent totally clean and use waterglass!

Do a search under me for using waterglass!

Fwiw, waterglass is Sodium Silicate and is the main ingrediant in h-d stop leak's.

I've used waterglass twice in the past and it worked fine!!

Re: BB Head swap

pdq67, What is this stuff and what name is it sold under? I tried to do a search without much luck. My online connection sucks and so do my computer skills.
