440 build questions and any suggestions.

The pistons are Keith Black KB237040-8. They have valve reliefs in them. I haven't mocked up the connecting rod, piston, and crank assembly yet to check the deck clearance. The person I got the block from tore the block down but did not do any work on it. I took the block and heads to a machine shop and the block didn't need to be decked. The heads recieved the bigger exhaust valves, new valve guides, cut down for teflon seals, and has been decked .015 for warpage. The shop did do some machining in the exhaust areas to help the exhaust flow better. I have Fel-Pro head gaskets out of their engine rebuild gasket set, kit part number KS2110. No idea the thickness of the head gaskets when compressed. Problem with the kit is no individual part numbers for each gasket listed. I'm gonna guess 11:1 compression. I know I will need some sort of octane booster. The local drag strip is an 1/8th mile track. Yes I plan on tearing apart my 1973 Plymouth Scamp. I decided not to keep her stock. Will sell parts off of her at a later time.
