By the time you pay for new pistons,rings,rebore and buy a Yella Terra head and have it cleaned up fit for use, you'd probably have spent more than dave is asking for his motor??
Just a suggestion

dose a 202 head fit on a 179 /186 i no it will fit but what about compression

any help

202 head has same combustion chamber volume as 179/186 head.
Compression ratio will be variable as the head may have been shaved at some time in its history ( very likely with a Yella Terror head ) which will raise the ratio from that of a standard spec head.
Only way to exactly determine comp ratio is to have the head chamber volume CC'd.

Hey Rick,
I got a 202 yella terra head thats been converted for 186(Valve guides plates) I'll chuck it in with Matts(SCK) Hotrod project that i'll be storing for a couple of weeks. A bottle shop voucher and its all yours! Will need to be cleaned up and needs rockers. I've never used it and don't know its history.
Cheers Theo Z........................
