My doomed 408 build

I am aware that the eddy springs are different. I do not have the OEM part number other than whats on the heads. They do not have the last digit of the part number to tell if they were set up as a roller or tappet cam. That is the biggest problem so far. I am going to go the way of Hugues engines recommendations and go with a Mechanical flat tappet cam Hughes Engines , EDM light weight lifters Hughes Engines , a set of springs Hughes Engines , Cometic head gaskets, and any thing else I can find should be about another grand total.... Ill have 7 roller lifters and a roller cam for sale shortly...

I have cut open the oil filter and there were no signs of any metal in the element.
Imagine that Hughes recommending a crap load of their parts LOL
Please sorry about the smart ***-ness just this whole thing again frustrates the crap out of me for you..
