I'm still on the 205 block and to date no issues on that side of things.

thanks for that,ive heard the 205 blocks dont like long studs is this right??so would an arp stud and nut kit be ok running 400bhp??

correct you can not long stud a 205 block!stay away from the arp stud kit for a 205 block as these tend to crack blocks!(although i think this is mainly because they do not get set up right!)standard genuine headbolts will hold 400hp no problem!

People want to try and make it as reliable as possible.
And because of the cossie paranoia.
