We did not check compression before we started. However, I should have time to do that on the new head tomorrow night, provided I can escape my kids' baseball and softball games long enough. I'll be sure to post up the results. Just curious... what should I be hoping to see on this?

Those compression numbers aren't bad. Ford actually says that the numbers are acceptable if there is less than 25% difference between the low and high - yours are very tight.

What's the mileage on your engine?

did you check to see if there are any codes stored in the ECU? even if the CEL is not on, there can codes flagged.

I will be curious to find out what the new lifters do.

I didn't think to check for codes since the light wasn't on. I will check - thanks!

There were no codes. I got the replacement lifters yesterday. They are used. They are very easy to compress. In comparison, the ones that are still on my old head, can't be compressed. Is it natural that they would be "softer" uninstalled? I'm going to try to get off work early today to get this done!

Thanks for all the help, guys!

Did you find out about the spongy lifters? I'm really curious to what your engine problem is.
