“Fly cut they said it will be fun they said”. During the crazy supply issue times I talked myself into fly cutting instead of waiting on the .040” gaskets that were months out. Not my proudest moment but maybe one of the most frustrating ones was botching that up in a big way. I was having issues with the lock collar slipping as well as the tool inconsistently cutting and I went too deep. That necessitated buying drop ins in which Ironically I waited even longer than I would have for the gaskets doh!

But now I’m afraid this fiasco is still haunting me as I think maybe I reamed out the guides past spec by going at it so long with the drill/lindy tool.

I’m still having oil issues; namely oil sitting on back of intake valves with # 6 being the worst.
I only used one head to fly cut all 8 intake valves and since one head seems to be the problem surely this is the issue?

Anyone seen this happen or maybe have suggestions for a mail to cylinder head shop that could replace the guides.

I’ve asked this elsewhere and it seems most people think it’s not likely I bore the guides out of spec. But I will say the fly cut tool felt kinda snug compared to valve at first and I polished the tool with super fine steel wool to make it fit better. Just curious to see if anyone over here had any ideas or suggestions about where the oil might be coming from. Rocker bolts do not go through intake tract.
