I highly recommend staying away from odessa cylinder head. I ordered the ones with a la pattern and got ones with a magnum pattern, could be a simple mistake but they said they spoke with me to confirm it was la style. And I said magnum style. ........ they never asked me that. They said they had my number and called it out and it wasn't even the right area code! My machinist disassembled the head and showed me where they took a head for 1.94 valves and stuck a 2.02 in there. The combustion chamber edges were sharp which will cause detonation. All in all very disappointed! I sent pictures and they swear the seats are cut for 2.02s but the dial calipers don't lie!
