Also, would a set of 3400sfi heads fit on my 3100sfi block? Are there any differences?

Oh, yeah, the flat tire story. I got my monte carlo rims for a guy with brand new cooper cobra tires on them for 400.00. That was this time last year. So, a month ago they start construction on a road by my house I take to work everyday. On my way to work, my lumii starts pulling to the left. when I parked, I got out, walked to the back, (thinking a dragging brake) felt the wheel, was fine, walked up front, tare was very very low. Drove to the nearest gast station becuase I was sure it would be completly flat after my 10 hours shift. That night when I left, it was still full of air. Drove home, went to sleep, woke up bright and early, 6am for school, walked outside, FLAT TIRE, on the rim. So i quickly put the factory steel wheel on, threw the flat tire in the trunk, and left. Got to school, went to patch the tire, unmounted it, and found a big hunk of steel, sheet metel in my sidewall. So right im sitting on 4 perfect shape monte carlo rims, and 3 tires with like 6/32nds tread left. So im running the origonal factory rims, and going to fix the performance problems before I buy new tires. Ha Ha, long story, kinda pisses me off. Anyone want 3 good tires? Cooper cobras p235 55 16's? Cheap? Just pay for shipping!!!!!
