leaky heads gaskets, I'm losing it!

All right everyone. After taking a few weeks off from cars to do spring yardwork I decided to put my big boy pants on and try this again. Same heads, heads have been shaved .025. Everything I read says that's no big deal. I cleaned the block and heads with razor blades and acetone. I used Fel Pro 521SD gaskets. No Leaks!! :). I feel vindicated. My LA / Magnum hybrid lives! I will only use the heavy duty gaskets from now on. I learned some small blocks have blind holes, some do not. I learned the Fel Pro 519SD magnum gaskets and the 521SD LA gaskets have the same exact holes except the magnum gaskets have holes for the pushrods. The LA do not. Thanks for everyone's input. Hopefully this will help someone else.
