6.4 crate into 68 dart

Afternoon folks, My new 6.4 crate engine has just rocked up and I’m working out fitting it into my 68 dart GTS, I already have the tti biscuit mounts and that’s it for now, I’ve gotta order the new sump etc etc.. just wanting to know if I can use 6.4 Jeep manifolds or will they hit the firewall same as these crate ones(I’m assuming they will going by they’re angle ) ... also with the TTi mounts can I use the 45 oil filter adaptor or need to go block off etc ? Thanks for the help, and looking forward to having the new gen hemi in!!
In my 70 Dart the 45 degree oil filter adapter fits but it is a mess changing the filter, but that's because of the tubular POS front end from Vendor "X".
