did you find oversized pistons? usually the pistons with a matching ring set are in the same piston kit.
that kit shows rings included. you choose the oversize you need when ordering it. you get 3 choices: standard, +.020", or +.040" . I would go with the 0.020" over sized so if you get 100k plus miles on it, you can go one more oversize to .040" on a future rebuild. but going with the larger oversize will give you a small amount more displacement, and slightly more HP. not much, but it will be larger displacement.

Re: Oh boy, valve knock? Video inside
I'm going .020 oversized so I can do another rebuild later on if needed.
So I actually didn't get the pistons from the kit supplier. I misunderstood on the phone so I'll have to find a set of those, which I think I did.

Re: Oh boy, valve knock? Video inside
Okay, so, correction. They did send me the pistons but they were shipped separately and took a few extra days. So I believe I have everything that I'll need. Finding a local machine shop with decent recommendations was somewhat of a pain but I think I found one. I should be all set to get underway on this.

Good luck Neu! I rebuilt a 4a for the Rusty Frog in a similar fashion. I can be a bit of a “nervous Nellie” on these types of projects, but things typically work out well.

Re: Oh boy, valve knock? Video inside
The goal now is to find a machine shop that can do it. Apparently all of em around here are booked up pretty solid(racing season) so I'm having to rely on friends of friends. It'll get done though.

Re: Oh boy, valve knock? Video inside
and an update! https://photos.app.goo.gl/NrwnNFeSY7HZNV667
Finally found a decent machine shop that had the time/willingness to do it. The cylinders are all over bored a bit, the head was compression tested and the valves were ground. Everything should be just about ready to go.
I'm waiting on a new oil pump and water pump(might as well). This is turning into a complete rebuild when I really just wanted to get it back on the road.
Oh well!
For anyone interested, they charged me a total of $465 to cleanup the block/remove material from the cylinders, rebuild the head, and press the connecting rods and piston heads.

Re: Oh boy, valve knock? Video inside
Great job on rebuilding the engine. How are the valves and valve seals? It is worth of checking them once you are that far in engine rebuild.

Re: Oh boy, valve knock? Video inside
I highly recommend install only new exhaust valves. New ones do not cost much, I have seen too many exhaust valves disintegrate with time, often trashing the engine when the come apart.
Well worth getting new exhaust valves when you redo the valves seats. intakes are safe to regrind and reuse if not worn out of tolerance. GET only new exhaust valves! do not trust old used ones.

Re: Oh boy, valve knock? Video inside
All the valves were taken out of the head, cleaned, inspected, ground and compression tested. They're all alright.

Re: Oh boy, valve knock? Video inside
It's still gonna take me a lil while to get this going. I was just involved in an accident in my other car(2017 fiesta RIP) and i'm pretty beat up from that so I can't really lift or wrench too hard. New oil/water pumps are ordered tho so once they arrive I'll spend a couple days doing nothing but this.
