Question about Head Gaskets? I've bought GM Multi Layered steel gaskets, but they don't fit, says 5.3 right on them, but they don't fit over the locating pins?? Looks like the bigger holes on the gaskets for the locating pins are at the top? The locating pins on my engine are at the bottom of the block surface? Is it wise to just get others? I don't know I feel comfortable grinding on the gaskets.

They don't fit. That's all there is too it. They even block the small holes up top.

I'll take a pic.

There has to be something wrong with them. I used the ls1 5.7 head gaskets on my 5.3.

Just ordered a fel pro set locally. Ugg these were expensive, I'm in Canada and ordered them out of the USA.

Did a little intake smoothing. Hope it fits under the hood. Not 100% sure yet.

Anyone used one of these intakes? It's cheap, considering I've really blown my budget. I can't use the truck intake. Too high.
