Be sure to let us know what you decide and what the results are. Inquiring minds want to know.

BUT . . . If the machine shop route is out of the question, and you are installing new valves, take a little extra time and put some lapping compound on ALL the valves, and using a lapping tool (suction cup on a stick) seat/reseat each and every valve. That way, at least you'll be sure that the valves that you are putting in won't be leaking (causing wire-cracking) from the moment you start 'er up. Also, you mentioned warpage on the valve you used to trial fit . . . . .Lapping will help to cure that, as well, if it's not too bad. IF it's bad, you need a new valve there too. After lapping, carefully clean with a good solvent, flushing out the port well. Use bluing, if you can find some, to verify that the the seat and valve are indeed contacting 360deg.

(Edit -- Brian, I just finished reading your post to the end. Funny how we seem to often think alike, at least on this thread. I think you've got some experience with hand lapping, eh??? Mine came on a TR-3. Worked well for a couple years. I think this is a Chevy II 4-banger. Not an overhead cam, so unless the chain broke, or jumped a good number of teeth, interference would not be a question.)

You're right about that Pat!! I have a electric drill motor technique my dad showed me when I was about 10 or 11. He's been an ASE tech for 35 Plus years. Not much I haven't seen him fix. I got the same knack. I can usually take anything apart and fix it but sometimes things are just to broke to fix. I have been in the diesel mechanic field for 10 years and am now a fleet mechanic, in the past I worked on everything from 60ft yachts to 6 in gorman rupp trash water pumps to 18 wheelers to weed eaters. I have had a wide variety of experience. I usually enjoy my work, then there are those times I would like to strangle a design engineer for building some of the crap they do and locating components in some of the places they do. Well gotta go get ready for work!!! See ya Brian

Brian.
I've used the drill motor too. Chuck it on the valve stem, pull gently, and let 'er rip.

BTW -- When you're angry at design engineers, please, don't let me get close. I do a little tooling design, and contribute some to product design. . . . .Anyway, I hope the work on the boat is progressing well.

Sounds like you and your dad are both really good "wrenches." My dad and I are both OK, but just hobbiests. He's gone now, but like you, watching my dad was where I got the confidence to do this stuff. And to experiment a little.

Bye . . . . Pat

Yep that's how we do too. He taught me to gently run the valve back and forth. Pretty much like the way the valve opens and closes during normal use. It helps keep the lapping compound on the valve face and seat, since it has a tendency to get pushed out of the way. Thanks Pat I always enjoy a good conversation with a fellow car nut. Brian

Thanks guys, I got it up an running and seems to be running great after replacing all four of the exhaust valves. I'm going to have the head redone after the season. Also had the carb rebuilt too and it seems to be running great.

thanks again for all of your help.
