you should check the intake fit but the bolt holes need to be sloted before you have to start milling the intake ports may or may not line up .this may not be a big deal as the intake can be milled or some port work or just leave it as is any more then 025off the heads you may want to see if the bolts will go in the intake i seen were more then 040 was off the heads and deck things still fit but you need to watch out for the intake rails will bottom out on the block use RTV here not the rubber rail gaskets. the steel shims i do not care to use. you need to find the cc of them i do not know. as for the heads i put them in the mill cc the heads to see were they are realy at. i make a 005 cut that.s per 1cc should be close but i cut then see were its at for cc.s in real life you need to know how big is the bore going to be as this can add to more CR. you not not want to get to nuts on milling the heads as you loose valve to piston room and on the intake side you do not have it to give up .what cam do you want a solid roller hyd roller or hyd /solid flat lifter cam ?
