Carnage from last night

[RT K_line]

Seems like coil bind might be the culprit. The Racing Head Service I'm familiar with is in Memphis and is mostly a Chevy shop.

Turns out it was indy after all I found the receipt for the heads.

They are HD 10 degree retainers I had added with my over size valves when I bought the Eddy RPMS from Racing Head Service which I found out was apparently indy. I had to send the heads back because I needed the open chamber heads for my step head pistons. The paperwork I got back said indy. AND I don't think I got the 2.19 1.88 valves I paid for. I guess I'll know for sure when I have to replace the valve that was damaged.

I found the receipt for the heads it was Indy after all where I ordered the heads.

I installed the 906s I had done for the engine originally. I had them resurfaced and swapped the springs over with some titanium retainers and 10* locks. I have driven it a couple of times and so far so good. No overheating or coolant loss and the oil is good also. I plan on driving it again then doing a compression check to determine the condition of the engine. So far the engine is performing better by a seat of the pants meter which I attribute to the ported heads and tighter quench of these heads. I will post compression test results asap. I'm curious about the max cylinder pressures also.

compression tested 5 cylinders I could get to the easiest. the affected cylinder #6 was 125 psi the others ranged from 122 psi to 128 psi.
