To fix or not to FIx

[JPCY72]

Hey Guys,

SOooooo my truck burns a lot of oil and I hadnt noticed it until recently.
Its burning probally close to a quart every 100 miles, only when Im coasting to a stop and when I rev it hard in neutral. I did check the compression in 2 and 4 they were both at 120 and the # 2 plug was oily... I have a set of smogger heads that are rebuilt and are 75cc 1.94 intake valve heads 462624 castings. My heads are 1.72 intake valve 74.5cc 339x castings. Do I put the new heads on or do I bother. I dont have the money to rebuild this motor now and I just want to tow with it and drive it occasionally .... what to do??? thanks guys
