Spoken for truth.
The problem with the blocks is getting guys to understand why you need to do it and then the cost.
It's even more difficult when a guy spends an assload of money on heads and valve gear and the seller tells them it's bolt on stuff and then you tell them it isn't. And then the seller tells them you wrecked their heads.
Thank GOD Mike came along and made his shims. Guys are much more likely to use his system than conver to blocks.
Now we just have to convince these guys their geometry needs to be corrected.
