use gaskets between aluminum intake and cast heads??

should i use paper intake gaskets with an aluminum intake on my 440 as well as using a stamped steel valley pan ????

any info is greatly appreciated, as i am ready to install the intake.

Thanks !

I did, got a set of fel pros for my performer rpm. they're included for a reason.

I think this topic has been discussed here before. They did not come on 440 or 383. They just had the metal pan. Mopar sells some stuff that is made for the metal gaskets and sprays out of a can. I have never had a problem when using that spray sealer.

i bought the intake new, but did not come with a box or gaskets, it's a holley street dominator....i have a set of paper gaskets i'll use as well i guess, thanks !

I only use the paper gasket on the side that the aluminum intake is against. No need to on the opposite side.

Never had a problem with just the metal valley pan but have when trying to use the paper with them.

You'll get alot of diff opinions on this. I dont feel that a metal gasket is pliable enough to seal 16 in hg of vacuum. Alot of times the added thickness of the paper will throw off the alignment & the bolts wont line up. My preference is to use the valley pan with #2 permatex,the brown goo in the toothpaste tube. It stays pliable, especially with the diff expansion rates of iron & aluminum. works for me.

I use the tin pan with permatex hi tack gasket sealer.

Have bever used the paper gaskets.

Threw out 20 sets here a little while ago

after trying to line up the mounting holes using the gaskets..i ditched them and resorted to some of the permatex #2 sealer.

THANKS !!!!!!!!!!

Best,
