so basically unless I get real creative with the runner, I guess I'd better not mess with it, I remember when I worked in an engine shop, old Fred used to say that most gain in the "porting" process would be gained in opening up above the valve and seat a widen it up, and smooth it out and work the bowls and throats out, should I have zero decked the head? If anyone has the software, could they tell me what CR I will have with a 261 block that has had 20 or 30 thousanths taken off the block, and I think its pretty much a stock 848 head, and flat top pistons? is there anyway to check and see/measure the thickness of this head? the shop that rebuilt it seemed convinced it would be around 9:1, but the pistons are nowhere near the top of the cylinder when they stoke all the way up. So stock 848 head, block with 20 to 30 thousanths off, and a standard head gasket, non coppper/non retorque type that is mesh and metal on the edges, thanks in advance people.


you can lead people to truth, but you can't make them see it!
