Hello everyone, I am new to this forum a friend recommended me this so I thought of asking about a Frankenstein swap/build that I am doing to my gs 1991 Integra that I’ve obtained for 1k$.

The car came with a b17a1 block stock / b16a JDM head. Unfortunately the ex owner had spun a bearing, regardless of that I accepted the challenge to experience how to rebuild a b series ( first time ).

I’ve found and bought from CT a block b17a1 bore 81.5mm and came with civic type r pistons, rings, b17 rods and b17 crank. It was wrapped in a box, unopened still after 4 years.

I assembled everything and gave me a good reading on the oil light/gap. Crank looked great, block look like it had low miles etc

I am also reusing the b16a JDM head that the car came with ( b17a1 stock spun bearing ).

So my idea was to swap block only and maybe upgrade its pistons ( in this case civic type r/ Nippon racing pistons ).

I sent the head to get a rebuild and resurface and came back looking great ( it was great condition regardless ).

So I am obviously new to the da9 b series as well since I’ve owned an ef si and crx before stock and restored from my part.

My question is do I have to check the valve to piston cleareance? How do you do it ? Anyone recommends any other methods ? Trying to acknowledge myself with experienced ppl as well so I would appreciate an answer from anyone with this kind of acknowledgement. Is it necessary to check the space between valves and pistons with this set up? Or should I send it ?
