i read your post on the the knifeartist's thread. my cylinder bore will be .20 over and the head and block havent been touched before, so with that in mind, what size do you think i should get? or should i just talk to horsepowerfreaks and they will help me?

you need to have the head resurfaced to use the mhg... and you SHOULD have the block decked also since you will have it apart.... then you can figure out what size you will need.... it will probably be the 1.4mm version.
Keeping quench area in mind, you can go with an 84mm bore HG and be okay at 0.020 That means you have a lot of size options to choose from through Cometic.
Honestly? I can't tell you from a computer screen whether or not your head is fubar. If its blown bad your head will need more work.
Remove the head and then check for yourself. Don't get horsepowerfreaks to help you decide the thickness, that's what your machinist is for.
Have him LOOK at the head, and if he has much experience he should be able to estimate the amount required to be removed.

im sorry i didnt add that, but my engine is getting rebuilt right now, so the block and head will definitely be resurfaced and it will also have arp for everything in the engine. since the cylinder bore will be 83.5mm should i go with the 84mm or the 83mm version?Idealsupra said:
You need to add whatever is removed from the block and head to 1.37mm to determine the MHG that will give you stock comp ratio.
Don't assume that the block and head are having their first cut measure it to make sure!

It's just a known quantity, I dropped mine to 8.26:1 so I can run a few more LB's boost safely on the fuel I use.
