Sounds like to stock heads I think I read.
The girdle is more for “cap walking”. I haven’t heard of a block twisting issue before – but if present, it should help with that (. . . I would think). Main Cap walking is a big issue – mainly with engines with high stroke and/or for high RPM engines. My stroke is on the high end – but not as high as many others go. I don’t plan on going high RPM – so I don’t think I will “need” a girdle. That tug-of-war is still going on in my head and is not yet sorted out.On the street, with an auto, you probably leave every light and stop sign off idle as the 'verter grabs and pulls the front corner up . . . will twist the car and probably the block, but to a finite degree.
Yep!Budw you know you need to check valve guide and valve job on those heads correct? In fact all aftermarket heads but especially the Chinese heads.
To use them is a act of defiance on my on my part. I got tired of being told to go aluminum, that stock cast iron can't make power.
I like working on them and proving that you can make power with the old junk.
