possible 360 build

yeah I have the flat tops and I have the replacement Magnum style pistons, both 0.030 over, both very little use.
but I am afraid of possible as yet unseen damage possibly to the piston out of #4 that crashed a valve..... I know the flat tops have not seen that sort of issue. both sets of pistons are Federal Mogul brand. I would like to combine what I have to the best engine I can hope to have..... I do like the potential of being roller cam ready being a Magnum block...
I have a cam here (an MP one that they don't make any more) I have to get the numbers from it yet again, once the Magnums came out people on the Dodge truck sites used to call it a "sausage" cam.... it was the cam that all the magazines used to advertise with an MP computer and MP shorty headers to take your "235hp" 360 Magnum to 300HP.... not saying this is the cam I will pick, just that I have it.... in fact I have a 2nd roller cam for a 360, a buddy bought it for his 408 build then decided that it was "too small" for the 408 but would be "good" for a 360 Mag...
as I remember thinking that one might be a little too radical for what I'd want.... again my knowledge of cam numbers and how one number effects what is a little foggy..... I have a thread on the B boy site right now about that very subject on a cam for a 318 in another of my cars...… I need to find some fundemental "cam-educ.," info..... so I can be more informed and be easier to pick my own..... ever since the 318 that I built for my Cordoba about 1986-87ish that was dependable but a bigger slug than it had been stock, I have been very "cam-shy" and have tended towards either reinstalling the original cam or if there was a reason the cam had to be replaced (wear, etc) I have tended towards a stock replacement or "baby steps" above that level.
but for this topic I'm far away from cam choice. Unsure yet whether this will end up in the Durango like I originally intended, in my 96 Dakota 4wd or possibly my 85 D150 in place of the /6 or my 80 Volare….. what I put it into will have to be decided before I decide on a cam. right now just trying to make use of some more stuff that I have laying around.
are there any aluminum aftermarket heads for a Magnum block that come drilled for an LA intake, as the EQ's could have been had? If this engine found its way into the Volare or the D150 it would definitely stay carbureted.
but lets hold off on that sort of discussion here, right now just wanting to get the short block safely together. the top end can be another discussion later.
