390 w/open chamber heads

OK Frosty The Punk...you got me. I got the 1.88 intake mixed in my head with the 2.02. You're right, I have a new set of Ferrea 2.02 intake and 1.6 exhaust valves as the pics will show.
I worry a little about the rockers. I have a set of adjustable rockers but everything I read says that they are not very accurate as far as being consistent on the 1.5". But since I'm not building a race car I hope it doesn't hurt me too much. Also I guess I'll have to buy some of those adjustable (dummy) push rods to get the correct length then buy a set of the ones I need. That part I'm not sure how to do since I can't actually do a push rod length test until I have the cam. I can't order the cam until I finish the heads. Then assemble the engine (mock up) with cam and lifters to get the push rod length.
How do you make sure the lifters are properly pumped up in order to get the proper push rod length without starting the engine?????????
