I have the one with the little pan made into it to clear the heat crossover. Used it for around 100 dyno pulls with Edelbrock heads and a CH-28 intake.
The only problem I had was after about 10 pulls it developed a leak where they welded in the little clearence pan. They ground down the welds a little too far before anodizing it. It cracked at one of the ground down welds.
I Migged it and painted it and have had no more problems. I use Ultra Black silicone,sticks well and cleans up easier than Right Stuff in my opinion.
I would think the solid tray would be fine if it will fit.
