why dont you ask him?
steve is a very honest cat, him or greg ( his son i think? ) both will tell you whats up.
my personal opinion is that they should handle that and then more. to get some more replies you may want to change the title of the post.. i came here thinkin it would be a clutch topic.
maybe tims stage 2 heads.

These Tims heads hold 14 to1 so 10-1 on smaller heads should be no problem.

The Stage 2's and Steve Tims' Signature race heads all start from the same casting.

The weld is simply to build up material above the intake port wall to allow for a larger port. It contributes very little, if at all, to the strength of the combustion chamber.

I meant if you can take that much out of a stock head and it remain durable the Stage Twos will be durable. Welding heads is just for being able to put the port where no aluminium was present in the stock casting.
Get the Stage Twos you won't be dissapointed. |

Just about ANY type 1 head will crack. It's a very common thing. The only place a type 1 head will crack is between the valves. Sometimes around the spark plug, but not as common.
People run with crack heads with no problems all the time. The only way to get a type 1 head not to crack between the valves is have the biggest valves you can put in them where the valve seats actually touch. But that not practical on most engines. |

Just about ANY cylinder head will crack. there. fixed that one for ya
It's a very common thing. yes
The only place a type 1 head will crack is between the valves. Sometimes around the spark plug, but not as common. sure why not.
People run with crack heads with no problems all the time. yes they do, doesnt mean its ideal.
The only way to get a type 1 head not to crack between the valves is have the biggest valves you can put in them where the valve seats actually touch. But that not practical on most engines. flat out period NO FALSE WRONG ANSWER |
i have put about 30k on a set of heads without cracking them and have seen heads with over 100k without cracks.
its all about how your setup and how you take care of your engine. make sure you have proper cooling, and proper warmup.
i dont know where you got your info from craig but i disagree strongly.

Cracking is caused by overheating.
Why are you so hung up on having 10.5:1 CR? What gas are you gonna use?

what method is your octane measured i know its different than here in the states. i cannot remember the differences offhand but im sure someone knows and will chime in with it.
the heads will handle but man that is ALOT of compression for a "fair weather" driver. im sure you could make it driveable.
but 9:1 with an engle fk-8 and those stage 2 heads from steve tims on a 2 liter make for a KILLER setup and 100% driveable
ask glenn lol
im not sure what his compression is exactly but its close to 9:1 im pretty sure.
