I whanyed to ask if type SH cams diferrent than just a regular H22 or are they the same? Thanks

 

Well this is what Crower has to say:



and helms says:

4th gen vtec and fifth base (info taken from 2 different publication Helms manuals)
intake gross lift: 11.4 mm .449"
exhaust gross lift: 10.6 mm .417

Fifth SH
intake gross lift: 12.0 mm .472
exhaust gross lift: 11.18 mm .440

But there is some contention about wether or not the cams between 5th base and SH are the same since the part numbers are the same. Same part numbers = same part so they may not be different.

Crowers SH lift info seems to be too close to the Helms' lift numbers for there to really be a difference.

Based on Crowers info and the part number fact I think that they are the same with potential minor differences between earlier USDM H22 models and later USDM models, where they might have changed the ramp speed and whatnot.
hope this helps

i thought that the SH had increased cam grind to compensate for the increased wegiht.

 

Remour says the SH high lobe is 1mm taller than the base lobes. Type S is .5 higher than SH.

 

if they are bigger its so small that it really doesnt matter
