Just bought some GT-40's (iron) for 275 bucks. They are ported to intake/exhaust gaskets and have new seals/springs, and come with crane
1.7 rollers and were milled .005". I was just wondering if I should get a valve job/bowl polish done given all the new stuff on them or should I wait till I really need to upgrade. The car they came off of only had 40,000 miles. I am leanin towards holley systemax intake/upgraded exhaust and jewelry to go with it as next project.
