I labled many of the plugs, and most of them should be easy to put back in place. Will see though, waiting on engine builder to call.

99% of the plugs are different so it's not as bad as you might think. Any plugs that are identical are likely going to be in completely different areas of the car.

When you say stock heads you mean as cast or ported??

I understand doing a shortblock as a repair and not being able to afford head work but just wanted to tell you a 300shot and as cast heads is not going to work.

I have seen a car gain nothing from a 175 to 200 shot because the heads could not flow enough to let it work well. Start spraying big shots without suporting flow and it displaces a huge amount of the NA flow and chokes up on the exhaust side and you stop gaining much if anything even though you put in bigger jets.

You have a valid point (or it makes sence to me anyway), nitrous is not going on yet, the heads will most likely be stock cast for now. Anyone want a dented fram oil filter has 89 miles on it lol jk.
