S/B decking

By the time you add the machining costs for cutting the decks, and then making the intake fit again, and after you decide you wanna try a different intake and have to cut that one too, and the custom length pushrods,IDK.And then you find out the machine shop cut it high front to back on one side and low on the other and they're not even at the correct angles and one side is lower than the other....IDK
If I can help it,I'm never going that route again. For me it will be custom fit pistons, and leave the factory machining alone if/whenever possible.
And that goes triple-gazillion for an align-hone. If they mess that up, it's possible that the rear main-seal will never seal! Or not seal for very long.And changing it every 10,000 miles, in-frame,gets old in a hurry!
KB hypers for me.
An acquaintance of mine, says he bored his 360 to fit some 340 forged slugs, and then cut them to fit his X-head chambers.I can't say if it's true or not, but his 360 roars pretty good. And does't leak at the rear seal.And he has tried several different intakes without additional machining costs.
