my stroke has to go back to the shop, its thier fault

Well as some of you know my SB stroker broke at an early age.. busted rocker arm adjusting screw which led to the push rod cup digging into the rocker arm sending metal into the oil the adjusting screw broke just under the lock nut ect.. any way I am taking it back to the shop for the owner to see, After talking to him on the phone he seems to think it was faulty parts (of course) but those parts lived on a stock block .030 SB 360 with same cam springs,heads non milled or decked ect..

Here is what i think happend.

First the engine was CnCed, decked balanced then assembled, upon assembly the assembler didnt check the Push rods for the correct length (reused the ones from the stock deck engine) and since the rods were to long he adjusted the rocker adjusting screws out to accommendate for the extra length. So now the rocker Geometry is off, the rockers now touch the valve stem off center,(not like they did before) so to correct this problem he used valve lash caps so the rockers would have a larger path to ride, so since the rocker geometry is off the adjusting studs broke under the uneven or stressed load,it may even had coil bind.

The cam is not to large for these rockers 488/491 lift according to the rocker company.

I know when I had the rockers in this engine before it was stroked there were aprox 2.5 threads showing above the rocker adjusting lock nut, now there are at least 6.5 to 7 threads showing, if i flip the rocker over the ball is resting near the bottom of the rocker, to the point it almost pertrudes into the adjusting screw hole. Even thou I used an inexpensive set of rockers I feel they are not to blame, I blame the machinist for not checking his work, now My stroker has to be flushed and torn down to get all the metal shavings out maybe even new rod and mains. When i called him a few weeks ago about the noises, he assured me it was NOT the engine ( guess he is God and makes no mistakes) When i called him about the rocker problem he said OH must be the poor quality of rocker, and the engine needs to be checked at my expence..

From looking at the adjusting screw threads, there is about an 1/8 in at least difference in the way he set them up compared to the way i had them on the stock deck with non milled heads .039 head gasket. If the correct PR was used I would think the Rocker adjuster would be in a simular spot as it was the first time 2.5 to 3 treads..I really think this is in thier (shop) error and not mine nor the part.. The shop assembled this thing from pan to intake including the valve covers, therefore they checked and assembled the valve train. Basically when i picked it up it was ready to go in.

Here are a couple of pics.

what do you think? I doubt he will take care of this problem, if he isnt willing to remedy this should I take it else where ,Heck i may do it myself..But first I want to see what they will do.

Thanks
