cylinder heads
well well well another head story sounds way to familiar! years ago i had a "machine shop" and i use that term loosly ,do a set of heads for my dragster. i took him the heads and a new set of intake and exhaust valves to install for me so i could go to the races that weekend. he got them "done" in time, i picked them up took to my shop started my usuall prep work[ i dont trust anyones work] i not only found that he just installed the valves in the heads he didnt even take the time to grind them! heck you could read thru them! just as i was ready to call him i seen a piece of metal that was between the valve spring! now i was mad called them up he said well bring them over and ill fix them. well he sorta did .i missed the race due to the valves just were not done right guides to tight intakes were seeping etc... i was pissed what did i do? i learned not to take anything to them again! and i went in debt and bought myself a valve grinder and i learned on my own stuff how to work it and how to do the job the correct way! im not saying to do as i did but thats what i did and still doing my own heads today!
