My current camshaft is 240/246dur. .573/.582lift 113lsa and my valve springs have 150lbs close seat.
In close future I will get a blower and I will change my camshaft. I think it will be 224/236dur. (classic blower cam).
The question is, do I have to change my valve springs after I get that camshaft?? What can happen if springs pressure is too much? loss of power??

 

Nope the same springs should work, and work well.

Its a good news. Thank you Bret!

 

The blower will actually put pressure on the backside of the intake valve trying to open it, normally you could have swapped to less aggressive springs but with the blower the extra seat pressure will just be insurance.

 

The springs came with AFR 210cc Heads, they have 170lbs close seat, but my engine builder shimmed them and lowered to 150lbs. I told him to get beehive springs (26918), but he didn't use them. I think I will wait until a problem occur. But as you said more pressure will be the insurance.
