If I were to swap the internals out of the H23 block on to my H22 block-What are the chances the piston would hit the valves.

And I having a hard time at work and I can't find the deck height specs-And the difference I see on the H23 block vs H22 is the stroke duration and the H22 has Oil jets ........Thanks...Let's keep it real Rocks

 

If you use the H23 Crank and Rods you will be fine. If you use the h23 crank and the h22 rods ur pistons will hit the head. The deck height is the same for both the h22a and the h23a. They are Identical p13 Blocks. hope that helps

 

Thanks....I thought It was reverse....If I use my rods I wouldn't hit the head.

 

Because the h22a has a shorter stroke at 90.7mm it needs a longer rod versus the h23a 95mm stroke which uses a shorter rod. If you used your h22a rods it would stick outta the block. So avoid doing that!! Hope that helps!
