Valve Cover Clearance With Holley Systemax

Mustang_GT_90 · 12-20-2002, 08:21 PM

I've read that some valve covers don't clear the Holley Systemax Intake. What kind of valve covers are you guys using that have one of these intakes, and does anybody who's been down this road have any other clearence issues?
Thanks

That intake gave me the most problems. I have tall valve covers to clear the stud girdle and the intake didn't even come close to clearing. So then put on a 1" spacer between the upper and lower and it still wouldn't fit. I had to grind some on the bottom of the intake to clear the valve cover and it still touched a little. I got it to work and then my hood wouldn't close

And that is the reason for the scoop that I don't like. It is a good intake for performance, but the victor 5.0 was easier to make it work and much better performance.
