ratsmoker,

I'm not sure if you read through the website, but... yes the author was referring to using 428 CJ heads on a 390 block and then milling to up the compression to 428 specs.

The text for what I'm referring to is located on[link:www.woodyg.com/fairlane/finfo/390stage3-4.html|THIS PAGE] located in the last paragraph/sentence.

I have much to learn...

THANKS!
