Relax. All it requires are some measurements...

...that your shop can handle. Especially if they are ordering the pistons (and presumably making some $$ off that task).

Compression height -- leave blank; Ross will figure that from the rest of the data

Rod length: I doubt that you will change from stock length, but now is the time to decide!

Chamber cc: Measure the heads. If you do not have them, get them. If you do not plan on doing any chamber work to them, ask Edelbrock the median chamber size.

Intake valve position: Sorry, you need the heads for this. Too many variables to use a median here. Ross need this info for CR and Valve clearance calcs.

Ring type/size: Chose the ring stack now. ZGS rings like a different groove clearance than file fit rings. 99.9% of the performance ring sets are stacked 1/16, 1/16, 3/16.

Head gasket thickness: Just choose one now. Example: Mr Gasket Ultra Seal #5760 is 0.042" thick. Note: this is not a gasket recommendation, just an example. I've never used Mr Gasket head gaskets ao I do not know how well they work.

Block deck height: have the machine shop measure for you. You also need to know if a cleanup cut is needed and how much. Your shop can tell you this.

Regards,
Dan
