ROGO Heads

[GeordieBoyKel]

I think this is a 650 but my question is, will it fit on a modded 701 engine without any problems?

 

[GeordieBoyKel]

Here is another question...

Why are some heads girdled and some are not?
Should cast heads be girdled?

 

[fals3illusion]

i had a high compression head for my 650 (180 psi) and i tried on my 701 and i only got about 120 psi compression,

so from my experience no you cannot.

itd probably be fine, but id get the right domes or have those ones cut.

girdle systems are to strengthen the cylinders, not the head, itself.

Its a cast head so you cannot change the domes... It would need machining I suppose...
