So the crap in my has tank made its way to the carb, which made it run like crap and destroyed the carb. I sent the carb back to Guaranteed Carburetors and they ripped it apart, cleaned it, replaced a couple things, and sent it back, only costing me the shipping to them. That was nice and easy.

Now it runs great, but still seems to be lacking. I did some fine tuning on the carb using a vacuum gauge and at idle, the gauge bounces between 18 and 19 inches. So now I'm thinking it's got something to do with the valvetrain. I've also got an issue with revs. It will not go above 4000 rpms.

I've also got an oil leak and the bottom of the intake manifold is wet. From what i can tell, the head gasket is leaking and the pressure from the cylinders is enough to make oil and/or coolant spray out and across the bottom of the manifold.

So at this point, I'm looking at the lash adjusters and a head gasket. I'm just trying to decide if i want to do just those, or go ahead and pony up the dough for a Clearwater head. My question is, what's the best for replacement adjusters and the gasket? When i get the gasket, I'd like to just get a full upper engine set and call it good on those. Thanks in advance.
