MMMH! Tasty Crow, my favorite! I had the heads redone with new exhaust valves, claiming it would still be worth it over aluminum heads or keeping the questionable 452's...NOPE!
$687 which included: clean & mag, 8 new oversize exhaust seats, 8 new guides, and all machining associated with installing guides, grinding seats and valves, making them all the same height installed, freeze plugs, etc...
I have a long list of the work they did. I would have been perfectly happy if it had been less than $600, but gee wizz it was almost 7!
To total the cost of the heads, for all to see (and ridicule):
200 initial purchase in 2014
70 for new exhaust valves
687 in machining
=$957 still needing stem seals!
Cost of new 440source heads: $998 pair + shipping + having them gone through.
Downside is I just barely beat the cost of new aluminum heads, they weigh more, and flow less. The few upsides are: I know everything on them is "right", none of it is made in china, and the money spent stayed in my local economy.
I can usually admit mistakes pretty easily, but this one hurts my pride a bit, lol. Think I'm going to run these heads for a loooong time to get my money's worth. What kind of beer goes well with crow?
Next time: CC'ing and port work! stay tuned...
