Replaced the cylinder heads due to a valve seat drop, chains, guides/tensioners, oil, and coolant and ps fluid. She fired right up. During my cheers of joy I failed to realize the need to open the vent petcock to allow the coolant to flow from the radiator to the block.........so after 1 mile, it shut down.

I've replaced both the Cam and Crank sensors. Turns over smoothly, but no attempt to start. Sparkplug shows no spark in a plug tester or when grounded the block.

What next???? Thanks!!!!

 

update: this morning after a couple attempts, I am starting to get some life, some chugging, but no starting. So looks like spark is present to some respect!!
