Blown head gasket= bad head???

[Capinoy123]

i would say no more than $75. and thats a generous number im throwing out there. what kind of head gasket do you plan on using? because that all becomes a factor to. Gosh is a great guy and knows what hes doing. He will let you know if anything is wrong with ur head.

every time you take off a head it will warp. ask any machinest and they will tell you this. when you take it off you will need to mill it down. now that isn't hard and its pretty cheap but they will probably find some bent valves also

That is not correct. Warping is caused by heat Yes, no head is perfectly flat, so it will twist some when put on (less than a human hair though, which is .003" - .004" BTW).

If you know the head was flat before and it was not overheated, then there is not point in taking it to a machinist unless you are having repeated problems. If you are blowing head gaskets because of poor tuning or too much boost, it will not normally warp the head.

In this instance I would get the head checked because you do not know the history of it. I just don't want people thinking that you need the head checked every time you change a head gasket and wasting their money.

Well put... and very informed.

isn't the tolerance for flatness on a dsm head .002"? Not that i'm one for sending heads out... I've never done it and have yet to blow a head gasket.
