lt1-lt4

So I was looking at putting an lt4 package on my lt1.the heads cam intake pack.does this change the compression at all?

to answer your question if you go from true lt1 heads to true lt4 heads, using the same head gasket thickness your compression ratio will go from 10.4:1 to 10.8:1. so your answer is yes lol but just ever so slightly.

FYI, there is also a slight miss alignment issue with the LT1 Intake to the LT4 heads.
The LT4 had a raised runner over the LT1.

To bad you didn't want this about a month ago, I had a complete LT4 kit for cheap
