Re: Vortec 8 bolt to 12 bolt conversion

Ayup, good link.  There were some early notes to use an intake
designed for raised port bowtie heads, but there's no sense buying the
wrong intake when the right ones are available.  

And you might want to know that the vortec springs are low pressure
parts designed to reduce power loss.  They're not recommended for high
rpm or high lift cams.
