hello
what intake gasket do i need to use a 99+ intake on a 93 4.0l ho head?
seems like there is a different gasket for both so not sure what to go with

I am thinking about the fel-pro MS93094 for the 1999-06

plan on gasket matching if that makes a differance

thanks in advance

Use the older style gasket

Jesse Byrd

cool...just out of curiosity do you know what the diferance between the two are?

tssguy123

Yup!



The red parts are from an 0630 head, and the grey from an 0331

If you use the gasket for an 0331 (2000+) on an 0630 head, it's going to cover the holes on the block a bit. Obstructing flow



On top is the newer style gasket, on bottom is the older one..

i belive the head is a 7120 (need to go pick it up this weekend), or do the 0630 and the 7120 share the same port design? it seems like the exhaust is the difference right? if so would it be beneficial to open it up to the 0331 design and use the coresponding header/manifold

edit....just relized that the 0630 it the larger one

tssguy123

You're right... 0630 is from 96-98. But I think the actual port design is the same
