I am familiar with the tried and true method of o-ringing you block in conjunction with copper gaskets, but I was wondering if any of you guys ahd tried anything else. I am putting together a blown GMC and it ahd headgasket blowing issues enven before boost( I will deck and chamfer head bolt threads)....my question is in reference to a visit i had a few weeks ago to a collegues community 'hotrod' garage. About 25 guys rant a 3 story brick building and each have thier own little work space....anyway, he was giving me a tour of the place and was showing me some of the other guys stuff and one had a BMW M5 that was gettinga turbo bigger than my head and he was installing some sort of sheetmetal looking compressable ring that you inset in the top of your bore after it is notched by you machine shop. Supposedly you use these things with stock type head gaskets? Every heard of them? I'm going to go by and inquire to get a name of the product. It just seemed offhand much cleaner and simple than that damn 041 wire, and being one piece it has no gap at all where the wire meets....that has always bugged me...Hans
fyi, I just started a thread on my blown 270 GMC build over on the Inliners.org forum in the 'boosted' section. I figure since it's for my street truck, I didn't need to take our focus away form racing since we only have 58 days and 13 hours till we need to be ready at the salt....I know several of you guys frequent both sites.
