Valve train geometry
Are all that brand heads that way ?
Yes, mostly because of all the variables involved in what affects the geometry makes it nearly impossible to locate the shafts for every conceivable assortment of parts.
As an example, when Indy came out with their head and it had saddles instead of using blocks I called them and asked WTF? How am I going to correct the geometry? He says if you know what you are doing you won't have to. So I ask, tell me what I need to know? He says run our parts and it will be correct.
I called bullshit and that was that. A couple of years later a set came through the shop. Customer bought the Indy package. The geometry was off. More than I care to let it go. So I milled off the stands and made the customer buy offset shafts and blocks. Fixed it. Indy told him I ruined his heads.
Same thing with their big block heads. I did a set back in 2007 and they geometry was sketchy at best. The customer was out of money so I let that slide, but it made me sick to do it.
This was long before I knew about Mike. Mike has now made it so there is no excuse for crap geometry.
I'm impressed by the number of guys who have checked out Mike, found him to be righteous and use his product. In the long run they will be much happier, and so will their valve train.
