Time to add some inexpensive HP

Going with the initial plan. Got parts on the way and it's going to suck waiting for the chance to start work.

Now I've got to get in there and give the engine a bit of a cleaning...

Is there a preferred gasket material/thickness for intakes?

I just use Fel-Pro print-o-seal gaskets. Don't use the steel shim gaskets on aluminum intakes. Put some sealant on intake bolt threads so oil does not weep through the threads. Also RTV in the corners where the heads mate with the block.
