it's definitely much safer with the 45 degree VTC. The only problem is finding a trustworthy place to get the 25 degree vtc gear machined.
The funny thing is, you can buy aggressive aftermarket cams that are safe with the full 50 degrees. It makes me wonder how dangerous it really is with the OEM cams.
majority of those cams tho are made for the K20 tho, to my knowledge they have larger valve reliefs... on the K24 the piston to valve clearance is pretty small, which is were the 50* VTC comes into issues...
