No problem do understand about the difference in expansion/contraction of aluminum vs. cast iron. Just never ran in to a problem before. Unless something is to extreme.
That's why, I'm sure, the OEM people install stretch bolts on their aluminum head engines.

Boy, you should try and tell a customer that has just blown a head gasket/head that besides gaskets, oil, labor, etc. He also needs new head bolts. They look at you with this glassed over look like you are telling them that the muffler bearings are bad....

I don't think you will be happy with solid copper gaskets. They are very hard and always seep. I use to run them on a turbo. They were great cause when the head would "walk" and try and lift off motor at full boost, the gaskets wouldn't blow. Just seep alittle, then seal up when everything came back to normal.

Have you tried the older factory white intake gaskets. If you can find them. Those things use to stick to anything. Were fairly thick too.

I'm interested in your problem cause I have a 351W stroker to 426 I'm putting together in my shop. Have ported Elderbrock heads for it. And DON'T need a sealing problem.

Let me know how you make out.

Thanks
