I have a question for when you weld up combustion chambers with the stock seats in them. If you leave them in while you weld with they have to be removed afterwards and put in a +.005 or +.010 seat to keep the press fit the same or does the press fit on the factory seats not change during the welding. I’m guessing with the spring pressure the heads see it’s not enough to worry about the seat falling out. I’m just comparing it to v8 I’ve done

[@ryanmorrow2058]

I’m welding a clone head for a buddy and I’m worried about the seats falling out after welding so we’re trying to find replacement seats and I was gonna weld up the register to stock size and put a new one in. His class allows welding and porting but he has to run stock valve size

@@ryanmorrow2058 I always take the seats out before I weld them now and replace them after welding. They tend to get hardened in spots from the tig torch and when you cut them they won’t seal. The hardened spots on the seats make almost like a hill on the seat since it’s harder material so seat gets wavy

Absolutely beautiful. Whats the compression ratio on these things like?

[@paulskartslifan4206]

This is a video of a bottom end. To calculate the compression ratio there are programs out there. Google how to calculate compression ratio. Since this bottom end is 300cc’s use the other parameters of your build to calculate it. They are variables on engines. This is only a part of an engine. Compression ratio is based on bore / stroke (bottom end volume) - the heads chamber size, head gasket thickness , piston placement relative to deck surface, piston domes or dishes etc.
