Ok, thanks for all the free info.

The carbon is soft ,comes off with fingernail.

Heads are "as shipped" from Muscle-Motors 1999. Guides are good but those spring pockets hold alot of oil. Maybe the seals can`t keep up?
I not so sold on the rings/pistons not doing their job.
It makes good power for a "junk" motor....
6bbl intake that isn`t any good
.590 MP cam that is obsolete
Stage^6 heads that were never any good
.030 3.75 440 runs into the 9`s @ 3,050lbs.

I will look for the source of the oil,and start FRESH,no block filler, and see what I get........
