Yella Terra heads and roller rockers for 253/308

[DANNY8]

We just got hold of another 253 which come with a few goodies. Just wondering if the YT lads can tell me for sure if these are YT heads and roller rockers. I'm 99% sure they are as the valves have YT on them, but yeah just wouldn't mind knowing wat the pro's rekon.

Also, wats the difference between 253 and 308 heads, would these be ok on a 308? Any pro's or cons? Or are they the same?

Cheers,
Danny

Yep.
They look like Bathurst25308 heads and ST2033 rockers.
Be carefull about running those heads on a 253 because the valves are big enough to overhang the bore so you may need to relieve the block to make sure they don't hit.

Thx for the info mate. Don't suppose u could give me a price on wat the heads and roller rockers go for hey? Just wanna work out if we've saved much by buying a complete motor with all this on it (plus a few other goodies) or if it would of been better looking around for a new set.
