Hey
Look at the Post #11. Check how close the valve head is to the spark plug exit hole & Thread?? This motor has oversized valves. and the travel angle when it opens . And the spark plug angle !! If someone index's the plug , so the J strap is at the exhaust valve . They will touch and BANG!!! I remember about 4 years age VRP in Cali. Had a spark plug crushing Issue! and even posted some of the damage . Then about 2 years ago the motor had a exhaust valve clearance Issue . from a Valve float at hi rpm . I’m now thinking quite different HUMMM

On these heads with larger valves, there is enough clearance between the intake valves and the spark plugs when the valves open. The valve float I had was from the stock valve springs. The one damaged valve was an exhaust valve which as you can see has plenty of clearance from the spark plugs.

Look Closer & Check Twice
You have had such Great luck. !! and those failures were not a cause of anything you have done. Just looking over your shoulder Bud.You can see the difference in my Heads with stock intake valve opening. and of coarse my apologies for miss identifying the valves

What size valves did those old VRP heads have in them? Where they Ferrea?
