Default Intake gasket port size???

Help? I'm not near my heads or my intake manifold right now, and I'm ordering gaskets...

What size are the intake ports on 186 Camel Hump heads? They are late 1969 large port (2.02/1.60) castings that are almost exactly the same setup as the 1970 186 LT-1 heads.

Thanks! :smash:

I'd order stock gaskets. The ports on my Brodix DragonSlayers were still smaller than the 1204 race gaskets I used. The gaskets were called "race" because they have the crossover blocked off. But they were for a stock 350.

The problem is, I don't know what "stock" gasket size is, and the Summit site has many selections...Hence, the need for the measurement of the ports in inches.

Thanks!

I just measured the 1204 gaskets I spoke about earlier and they measured 1 1/4x2". They were more than enough for stock sized ports. Having a bigger than needed gasket won't really matter, but it will if the port on the head is bigger than the port opening on the gasket.
