What size AFR heads are you going to run? Cometic MLS gaskets? Head studs? Make sure you have the proper RA finish on your block with the MLS gaskets - heads should come with proper finish already. You have mostly blind head bold holes in the 502 block, so shouldn't be any major concerns with sealing the threads. Follow Bob's advice and run a good, stout set of pushrods too. You're gonna be a happy boy.
Borgie has been a HUGE help to, very knowledgeable and helpful.. Thanks again

So maybe someone can give me some insight, my block is as follows "14096859 Big Block V8 502, 4 bolt, Generation V, HO" From what I have read this is a marine block with thin main bulkheads.
Is there a difference between a standard 502 Gen V? What is "Thin Main bulkheads"?
Thanks

As pleased as I was with my engine I still had some issues that needed attention and whoever built the built the engine before used some street parts which after time is an automatic failure, with the EFI and Bobs recipe it's nothing but great times ahead

Make sure you do the necessary upgrades on the marine side. Big oil cooler/lines no npt 90's ect ect. I would put a decent oil pan on it to. More power more rpms means more heat.
Then after the motor is squared away probably gonna want hydraulic steering bigger trim tabs and the list goes on. Oh! And if your boat doesn't have motor plates in it you really should add them 650+hp will rip the stock mounts right out of that thing...

So last week and this week I have been on the phone with Bob and getting a serious education, as many here have said and I will reiterate Mr. Madera is 2nd to none with knowledge and sharing his education, a true gentleman, scholar and one of the nicest people I have met/ talked with.
Next week I will be ordering the pistons and connecting rods (JE Piston 4.500"x4.00"_6.135" + 7cc Dome and Connecting Rods, Forged 4340 Steel, H-Beam, 6.135 in. Length) so the machine shop can get started.
