LT1 intake possible coolant leak???
I'm in the process of converting my lt1 intake millican style. I've got all the bolt holes filled and just put on the gasket to mark where to drill, but i think the coolant ports in the intake gasket are way to close to the edge of the manifold for a good seal. Has anyone else noticed this and is there a solution? I havent heard any mention of this being a problem before.
Thanks

I always used RTV around the coolant holes on the head anyway. LT1 intake or not.
I also highly recommend it with this intake. There is material there just not alot. The ones I have done have not leaked except for my protype one that I'm running. See the coolant passages in the TF heads are smaller then stock heads. The coolant fittings I screw into the intake came in contact with the head and forced the intake away from the gasket causing a leak. I had to shave off some of the end of the fittings and use RTV around the holes. no problems now. I have been running it 6 months.
