I pulled apart my spare 75 2ltr down to the block (didn't split the case) that I'm planning on putting in my 75 project car. I also pulled the heads. My intentions was just to clean it up, do a visual inspection on the heads and re-seal the motor. I was going to take the heads down to our local machine shop to have them cleaned and if necessary a valve job.

I'm looking for some advice on whether I should remove the pistons, have the cylinders honed and new rings installed? Is this worth doing on these type of motors...or do most just buy a cylinder and piston kit?

Looking at all the kits available make me wonder whether to go with the stock 94s or a big bore kit. I see Jake sells a stock Mahle kit for $284 and the big bore kits are between 3 and 4 hundred elsewhere. I have both stock injection and weber 40s...probably go with carbs. I don't want to split the case to replace the cam.

So what do you think? (you can tell from my questions, I'm not much of a mechanic...but I like doing things for myself)

you don't tell us how many miles are on the motor and that info would give different answers. the "best" answer is that with any disassembly it to take it down to the main bearings (all the way to "do it right the first time"). some hack mechanics (ie, me) didn't do that to their motors. it's not that much to take the p & c's off to hone and re-ring. it would be nice to know the spec's on the p & c's if they are within tolerance. my motor had low miles so i had the p & c's cleaned and honed, new rings and refreshed heads. but my car is not used that much (weekend pleasure driver) and i wanted to put it on the road to drive it (and CSOB). if the motor ever needs refreshing again, then i'll upgrade it but with the low mileage i put on it, it might outlive me.
