Dean I wanted to say thanks for the post. Looks like I got some tough choices to make.
Hey, no problem, it always feels good to help.
But remember, when on a budget, sometimes ya just got to throw it together with the most sound parts you have and enjoy it while you're saving up for the better combo.
Well Dean not to go OT but and not to be negative but, when you have someone who puts a lot of stipulations on you and keeps you on a tight budget and throws a lot of things around upon you it makes it a tough situation. Anyways, thanks again.

if you are on that tight of a budget,magnumminded,i have a stock 383 magnum cam/lifters (just pulled out of a less than 60,XXX mile 383 from a 69 roadrunner) i kept the lifters in order. you pay shipping,and they are yours. that way you won't have to shell out for new valve springs,and it will be better than your stock 2-bbl cam.

Check the cc's of the heads and we can help you further.
If the 452's are equal to the 516's use the 452's. Reason being, hardened seats, 1.74 exh. valve, same compression, slightly better flow.
Ideally you want the compression of the 516's (w/the milled 452's) with the benefits of the 452's. And sounds like they are close.
If both sets of heads were equally worn and untouched, I'd update & freshen up the 516's. Just my opinion.
Cc'ing a set of heads can be as easy as putting some old spark plugs in, filling the comb. chamber with Play-Doh, cut the clay level with the deck surface, and then pull it all out and drop it in a beaker/measuring cup with a known amount of fluid. What ever it registers as a new amount is your "cc's".
use the 516's because of the quench??

Why wouldn't he need new springs? That cam used a different spring than the 400 2bbl.

What quench? In the original post he said the piston was ".100 in the hole". Never gonna happen.
i didn't mean cause of the quench,i meant use them becaue of the closed chamber,sorry i goofed up.

i had the ported 452's checked and they flowed 245cfm on the intake and 205cfm on the [Email]exhaust@.550"lift.not[/Email] too shaby,think i'll be buying some better pistons to utilize the head flow?
that's better than stock , yes a piston that was closer to zero would be a better choice to bring up the compression . Did you have a chamber Cc'd to see what they were ? Did I miss that in the thread ?
