8F2 Heads

[Racingfred]

First off, are they better then 8a7, 8g9, 8j0 heads?

PS. Looking for 8F2 heads, will put up a set of NOS set 8f2 rings for trade. Thanks Fred

8G9 head volume is 21cc. 8F2 head volume is 18.5cc and i think 8J0 has something between these two.

Sorry about my wrong info....

Thanks guys. Are the 8F2 heads small or large stud bolts? The one I have fits the larger ones, is this right? When did they switch?

 

[Reimond]

If i remember correct there was both on -77

 

[henke]

-77 was only small studs.
How big is the 8a7 heads?

I think somtime in 78 they swithched to the bigger bolts. I have seen post that some 78 heads had small bolt holes. Both set of 8G9 heads I have have large bolt holes.
