Syclone w/ FAST.
Vortec's lack an EGR passage compared to stock LB4 heads.
To make the EGR at least visually/audibly functional, I was thinking of drilling a hole into the exhaust manifold & running a stainless hard line to a newly tapped hole before the EGR valve. This will at least cause the idle to drop when the SMOG tech depresses the dashpot.
Do you think they'll fail it for a visual?
I don't want to drill any extra holes if it's not going to get me anything.
I always have the stock heads I could put on, but that's a real PITA.
