help with newer top end combo

What ever you decide to do for a cam change the springs to a set matched for the cam shaft. Don't make any assumptions on the springs. You will need to know a lot more about your short block to figure out what to do with the heads. At the minimum the part number on the piston and the measurement of how far down in the hole they are. With that info and the CC's of the heads you can see what you have and if you can get where you want to go. If you decide to angle mill the heads to get the compression up you will need to also do the intake. Then these two stay together for ever. Then I would look at getting the heads flowed and picking a cam to work with what you have for heads. All this adds up quick to make what seems like a good deal work and can easily run more than a good set of new heads.
