what lenghth intake manifold bolts do i need?

I need intake manifold bolts for a 302w with a funnel web intake i know they are 5/16 but what length do i need? Thanks for the help.

I would have to look tomorrow on my small engine and let yah know
[addsig]

The lower intake manifold to cylinder head bolts on the 302 are 5/16-18NC x 2 inches long. Just bought a set for mine.

PS: This could change if your manifold's bolt bosses are a different depth (don't know why they would be). Start with the stock 2" and measure from there.
