Wow! What a lucky catch that was Mike! Thank goodness it didn't get worse before you caught it!
How's that new build going? Anything new to post about progress?
Nothing too new. Been doing some wiring for the large electrical cables and am waiting for my welder to make up some fenderwell headers for it. Took forever to get the header pieces, everyone is so backlogged and slow right now.

What's that old saying, you play you pay? Just prior to my last race at Bremerton Raceway I heard the exhaust tune on the passenger side of the 38 change. I checked plug wires and looked around and didn't see anything and it was running fine. I ran the last race and got put on the trailer. When I got home, I pulled the valve covers to see if there was something going on. View attachment 107600 Even with the rocker arms on I could see the wear marks on my #2 intake valve. After pulling the arm shaft off this is what I saw. The valve was almost sucked all the way back through the valve retainer. OMG, did I miss a bullet. Little bit more and it would have ingested the valve as lunch for the piston. I am waiting for a part to tear down the head to see what happened, if a keeper broke, retainer slipped. Don't know yet. But heads are off and waiting for tear down. The face of the valves and heads look good so far.
Good catch. Certainly dodged a bullet on that one. Hope you get it fixed soon. love the wheels up picture too.

Just a little update. I tried taking the valve retainer loose to pull the injured valve and could not break it free to get the keepers out. So off to Napa. They broke it all down with their special touch and found that the valve was still in good shape. The keepers were egg shaped at best. Looks like high valve float at the top end of my last couple of race runs. Everything else looked good. So new valve job and seals. Replaced the 7 degree retainers and keepers with 10 degree set. Had to order a new set of roller rockers as I could not locate one rocker to replace the worn one from that valve. I am headed to someplace warm for vacation and then I will get the old girl put back together and back on the road.

Sounds like you're going to get it done without too much pain in the wallet Mike! That's good news! Have fun and stay warm on vacation!

Hi all, back from vacation. Got the heads from the shop, They are all cleaned up and ready to rock. I even had quick shipping with in stock items for the roller rockers (surprise). Started final cleaning and began assembly a couple of days ago. Got the passenger side head on and torqued down. It seems to be the harder of the two to reach. Dead timed the engine and double checked the distributor. Everything seems to be lining up. Hopefully tomorrow get back out and get the other head on and the valley pan. I am going to rebuild the carbs while they are off, so that will take a bit more time. But with the rain and upper 40's temps, the shop is a good place to hide.

You must have heat in your shop Mike! Mine's not much fun with the temps lately. Good to hear the vacation went well, and the heads are done!

I finished up tightening down the heads and finally got the rocker rails shimmed out properly. I get to assembly lube and oil everything up and do final assembly now.

I put in a propane heater in the ceiling aimed at the car bays. It isn't enough to spray paint with, but keeps the garage useable during cooler weather.
I don’t know that I would do flammables in the garage anyway Mike. closest I came to that was kerosene heater at the garage door with it open, then shut it down while spraying. Lol. Unless you can use water base paint. I’ve never used that stuff.

Glad you're getting close to finished on that big block. Youtube it for us when you get it running. I would love to hear it.
