my quess is it is going to be really tight, i am going to say flycut pistons is the only way...
dont know the clearance on afr's but my 230/230 on a 111+2 only had .086 on the intake with stock mls gaskets

That cam is in the realm of a G5X3 (234/242 112+4), which clears according to Louis at LG Motorsports: post
Because of the additional valve drop, you might be ok. You should still check PTV once you get it all mocked up, and avoid the temptation to run a thicker head gasket for clearance, it will invite detonation with the wider quench and high compression.
Also, look at posts that Chris made when he installed his cam. You can usually degree the cam a bit if you are on the border line and gain a few thousandths clearance.
Good Luck!

There is 200 thou of valve drop on a stock motor.
Any X series( G5, X1, X2, X3, X4, 111/112/114 excluding the xX ( which in most cases, thats install only here at the shop) will fit on a stock engine, 112 or 114. The X3 110 will not clear stock heads, but it will be close on the AFRs. You gain quite a bit of PTV with AFRs. If you are not sure, and want to know what your setup came in at, check it.
