350 gas and LP head differences

53SuperH · Dec 26, 2008

What is the difference in the 350 gas and LP head? Looking in the parts book gives a different part number for each. I know there is a different compression ratio between the two. Is this due to the head or pistons? Is a 350 LP head hard to find?

Thanks

the lp head has a smaller combustion chamber in the head. pistons were flat top ones from the factory for all except the high altitude ones. they are not that hard to find, just hard to pay for.

Does anyone have a pic of the different heads combustion chambers? The head i have has a casting number of 361479-R1. I dont see that number in the parts book, but im assuming its a gas head.
