I have used both the KB 402 and 403 in mild stroker...

...applications and they work very well. If you plan on turning some RPM or using spray they are not really the best choice for that type of application. The most important thing to remember when using them is to follow the ring gapping instructions to the letter.

KB site says pistons will be above deck.

yes the early blocks are 10.300 or there abouts. If you deck the block a few thousenths the pistons will be out of the bore a tic at TDC. For a combo that does not run over 6K this is not an issue...
