So are you going to swap the heads or change the valves? Nice you now know the cause. Personally I would swap heads as it gets you on the road faster. .

If you already have the valves out, then Lapping is a good process to get the compression up and add a bit of power. Worth the effort for sure.

So I lapped all the valves last night the intake valves look great but the exhaust valves I think I might re lap those again. I had a hard time trying to get the lapping tool to stick onto the exhaust valves.

An alternative is to use a short piece of rubber fuel line on the stem side.

Ahh I know I'm just answering yalls questions. Now I did the other side an it's kinda sorta leaking a lil bit of mineral spirits through the intake valves. But I went ahead an put it on the bike. Should I take it off I did attempt to re seet those intake valves before I put it though but idk

Thinking you may be fine. I have not tried the mineral spirits leak test and think many fine running bikes would leak just a small amount. I suggest going forward but other can freely argue.
