Click on B-series tab.. click on the respective engine component boxes; head, block, crank, etc.. on pistons, click on other then add the specs over in the spaces provided, same for headgasket. Which headgasket you plan on using. If it's a custom, add specs in space provided.. when you've filled your fields, hit calculate on the bottom, read results!

I know how to add in the info but I don't know how to read the results to determine if the oem gasket can be used with these pistons, I can post the specs of the pistons here an one of u can tell me that wud be good

look at overall compression. if it's to your liking use OEM. if not, use another thickness from another company.
don't make it more complicated than necessary. you can do it.. have faith in yourself

It's not the compression I was worried about why I asked this question it's the valve clearance with the pistons, I wanna know if the Valves will touch the pistons if I use oem head gasket

Again, that had to be calculated based upon the changes in the cylinder head chamber. some valves clearance fine while others may not. you may have to doi what my builder does and clay the engine to find out. that's why knowing the thickness of each gasket is important. this not a Yes or No type of question to answer.

Each engine will be a little different. There are so many variables involved in calculating P2V clearances (cam, amount of machine work done, rods, pistons, setting on adjustable cam gear, head gasket thickness, etc). This is why people degree or clay engines.

Yep. I give up at this point. you may have to understand engines a bit better to understand that your question doesn't really make a sense in this stage
Guys just want to know if I can use a oem head gasket with wiseco 6542m81 pistons in my boosted b16 motor or do I have to get a thicker gasket
If you are wondering about the thicker headgasket requirement on their .PDF yes. I asked wiseco the same quiestion 2 years ago and got the same answer. You must have a thicker headgasket on the B16 for god knows why reason.

I called wiseco on 2 different occasions asking them and one tech told me yes I need a thicker gasket and the second time I called another tech told me I absolutely don't need a thicker head gasket the oem one is fine, which is why I'm rather confused, I'm in Jamaica so I only Ave direct access to the oem gasket, I would have to ship in a gasket if I'm gonna need a thicker one
Firstly you must be dam sre your block dont need 0.5 larger pistons due to oval and since these pistons have 29.85mm compression height id feel safe not to run them
without thicker headgasket...
Those pistons have allready 0.15mm lower compression height.
Wiseco asks for 0.040 headgasket.
Oem is 0.026 so 0.040 - 0.026 = 0.016 = 0.4mm i dont think youll have problem with THOSE 29.85 compression height pistons.
For the others with 30mm comprerssion height id go with 0.040 requirement. I wanted 84mm pistons and all had 30mm compression heihgt thats why i went with cp.

OK so this is the specs for the piston in question and the results I got for the zeal calculator, my engine bore is 81mm, b16 head an block, I'm not sure if I entered the correct dome settings for the pistons

Looks to be decent compression and plenty of P2D height.

Did I put in the correct ting for the dome based on the piston specs? And does this mean I can use the oem head gasket without the Valves touching the pistons?

Looks like the specs were entered properly. Looks like you can also actually use a thinner headgasket, or have the head resurfaced and the block decked as well since the piston to deck height came out to .028
