I got my gasket kit from napa and there is only a 1 peice valley tray? do you use sealer with this or do you just torque it down and it forms a crush seal? I have never done an intake swap on a BB before so excuse my ignorance. I also would like to know the pattern to tighten the bolts and torque spec's for the intake. so if you would be so kind to go over the procedure for me that would be awesome..thank you! 1965 Plymouth Belvedere II hardtop

RTV will work just need the specific "color" that will resist gasoline and coolant on the intake ports & the coolant ports. live every 24 hour block of time like it's your last day on earth

I wrote it on the back page of Senatores book so I will know where it's at when I need it. EDIT I was thinking that the torque spec is 35 now that I think about it as 3/8" coarse thread(16 tpi)bolts are common for us & alot of them that size are listed at 35 ft lbs but yours & my 77 shop manual says 45 and my 1967 "glenns" says that BB intake manifold torque is 50 lbs which for sure is too much.

I have a Weiand, and bought a FelPro valley pan which came with the (4) gaskets mentioned above. I use the Permatex goop for everything, I love it, is that enough with just the valley pan?

I'd toss the paper gaskets, use your favorite goop(if RTV which I dont like for this) use a gasoline resistant color & 35 lbs in his pattern & you're good. live every 24 hour block of time like it's your last day on earth
