Motor build up combo looking for opinions remarks

I probably should have dome more home work on the head choice rumblefish
but i already purchased the heads off another site. I havent recieved them yet but since there paid for i'd like to make them work. bgr racing pointed out about the valve shrouding, glad he did. I believe by having the top of the cylinder walls machined that can be corrected. I got a call in to the machine shop about that. I am glad i found this site . Good people with helpful information here. Thanks

Ps. I need to go .030 to clean up what do you all think about .040 vs .030?
Should i do the minum bore needed? .060?
