anybody got a spare all pro 6 bolt head? i have one with a crack that was not repairable; need a replacement.
from what Bob tells me its the first version 6 bolt cathedral port.
figured only people here use the 6 bolt heads.. any better place other than my existing wtb thread?

i am not on yellowbullet
i use stock rockers, .600 lift cam, 921 springs, 6500rpm shifts
no that picture is when they were new, i didn't photo them currently.. was just for reference.
the crack is around the back corner of one of the lower main bolt hole pockets.. how it got there I have no idea. nobody is taking responsibilty for that. I bought the heads part of my longblock pre-installed through w2w and they were on the car for 1.5 years before sending to bob who noticed the crack. I will say the car had always lost a tiny bit of water i assumed ''came with the territory'' but i noticed a stain develop from the place that was eventually determined as a crack. see attached for the 'stain' pic (taken 6/09)
when bob noticed the crack he suggested a repair which was attempted and charged for but was unsucessful.. and unfortunately went from a little wet spot type thing to an actively dripping type of thing
i sent the head back again and i am with bob that the more that it gets cut into the worse the head will be structurally.. not to mention time and money thrown at a mere attempt with no gaurantee.
the real ball buster is that this version is no longer made and he has no spares, so i will need 2 new heads.. and i just spent $1200 to refresh and 'fix' these.
i talked to greg at trick flow today for some time and he said they havent ever had any cracking but of course that may just be a salesman doing his thing. maybe not. I also got some words of wisdom from Shawn@vaspeed.

A couple of things that sound interesting on this thread that made me think.
1. I have only seen 1 All Pro head crack, it was on a high power turbo engine that was around 2 years old. This was from the Ohio boys car, and they run the stuff hard, fast and often.
2. David ran his heads so hot at the LSX shootout the valves tuliped and he needed to tow it home.
3. Bob said he offered David new heads at half price.
The All Pro head is a proven performer, as is the TFS in my opinion. Cary has also refined the old ET line and added some new parts that look promising. I have one set of his newer stuff that Mast sells that look great and I anticipate great things. All three of these companies build nice 6 bolt stuff that will work well.

1. I have heard (not seen) otherwise, though i argue that my crack is not performance or horsepower related.
2. yea also i got some advice on raising the timing just prior to this situation unfolding that i took.. whow knows what happened really, the car was completely reliable up to that point (not taking a shot at the advice, but i thought it was interesting
. ) anyone in the loop may (or may not) remember my mention that the car used about a dixie cup of water here and there from the get-go. (the stain existed before the shootout (was there before 2008 shootout!) and not caused by it)
3. the half price offer is the best thing going and i might have to take it. I'm not scared of all pro heads now, just concerned. (you know i aint got no money) between the original refresh/repair and the secondary casting swap offer it would be a $2500 deal just to get back to where I was. I gotta do my best to put my money in the right place.
I am not here to thrash all pro, i'm here asking if somebody else has an extra like mine i can buy because that is my preference.
If i WAS to form an opinion tho based on the timeline there would either have been a defect in the original casting or there was some mishap during original installation. I think both are water under the bridge at this point.

And here is a picture of LS2Formula's cracked TFS245 6 bolt head. They called it a "shifted casting". We called it a "huge pain in the ***".

[QUOTE=98Z28CobraKiller;13095076]And here is a picture of LS2Formula's cracked TFS245 6 bolt head. They called it a "shifted casting". We called it a "huge pain in the ***".
The TFS water jacket has been revised and reinforced since this early casting was made.
