Re: 5.3 head Compression???
Probably nothing. They valves are smaller so you have to change them. 1 point of compression is worth about 20 HP. But it will all equal out to the same if not a loss of HP. Best bet is to get them ported and some new valves to use them to their full potential.

If you have a set of 5.3's and for all the work involved think about getting a set of ported heads from >>>>>>>>>>>>> there.
TEA has excellent heads. TEA Stage 1's are very affordable and will make good power. Also the Stage 2's are nicely priced. If your going to swap heads, get a good gain out of it.
