How much gap is too much??

[badbuik]

I'm getting ready to install my intake on the "Nitrous 470" but have a concern. When I set the intake down to check the gasket thickness, and the gap between the block - end rails and bottom of the intake, it seems that the .062 composite gasket is perfect, but the end gap is at 1/4 inch, and without the gaskets, it's 3/16, like I said the intake gasket thickness seems perfect, the ports all line up great. It just seems that 1/4 inch of silicone may be much. Yes, I have read the previous posts about silicone abuse, and its' been awhile since I put a motor together, maybe 1/4 inch isn't a big deal. Alittle extra info.; the block is decked with the piston .012 in the hole, about .015 off the deck, and about .036 milled off the Track Eliminator heads. Thanks, Gary G

Gary,

Your saying that .036 was taken off the heads... did they take it off the intake sides too?

Are the intake bolt holes in the head, dead nuts in the center of the intake manifold bolt holes?

At any rate, use the factory end seal.. it's .210 thick, and then use a small bead of "The Right Stuff" gasket maker on top of the end seal.

I would recommend glueing the end seal to the block, with 3M Black Super Weatherstrip adhesive.

Let the whole works dry for at least 24 hours before firing the motor, and it should be just fine.
