I bet this question has been asked and answered a bunch of times on here, but I did a search and couldn't find any. I'm not good with computers, so that could be the reason.


I have my 350 Vortec engine I am going to build for my T, and was going to use the 350 heads that came with it, however, I have just been given a brand new set of 5.0 Vortec heads free, so I would like to use these for obvious reasons.

I called my machine shop guy, and he says they will work fine, and that it is done frequently to raise compression, but he didn't know how much it will raise it. I also understand there are two versions of the 5.0 heads, one with a 1.8 something valve, and one with a 1.9 something valve. Mine is 1.8 something.

Not looking for high flow or performance, just a good running/ dependable engine, so I have two questions:

1) How high will the compression ratio go with the 5.0 heads? (I don't mind running hi test)

2) Do all the stock pushrods and all from the 350 roller work?

Thanks, and sorry if this has been hashed out before.
