429 stroker/build question Newbie!

Hi I am new to this site and from reading the threads everyone here is friendly and has a great knowledge about things which I thank you all very much.

I am looking to build and install a built 429 into my 71 mach 1 that has 36k original miles on it and been in the family since new, it originally came with the 351c that is in it now, I am looking to take that out and store it so I don't beat up the original motor due to it already being completely built up in the mid 70's, and I have a feeling that the motor may be getting tired from all the passes on it lol thanks dad!

Now for my Question I want to do a 501 stroker kit in the 429 do I have to use 429 rods or can I use the 460 rods that come with the kit. I know that the 429 and 460 piston pin locations are different from what I have read, will the 460 rods work or do I have to use the 429 rods. I am looking to get some aluminum heads any suggestions on a high flowing performance reasonably priced heads?
Sorry so long of a post just kind of excited to get this going and meet some of you guys. Thank you guys

Use the crank, rods, and pistons that come in the kit. Welcome to CHR by the way! Sounds like a nice old Mustang, hope you get some pictures of it up for us to see!
