For all the gearheads out there

Thanks guys !!

The intake and heads are aluminum so the gaskets were torqued to 25lbs both last time and this time. I started at hand tight, then 15, 20 and finally 25 twice
The port openings on the head are less than an 1/8" taller than the manifold
I think it's the gaskets being a smidge too big for the application and not getting enough purchase on the inner of the ports

I hope it's the last time I have to do it but as I said if it's an issue again, I'll get the factory gaskets from GMPP
