Hey Randy,
  Just checking if by chance you had the right part # for the Cometic head gasket. I will replace it as I have one on order.

Thanks for the ride Larry! It’s been many years since I’ve heard a B model air starter. My first job was at a gas station that Allegheny Freight Lines fueled their trucks. They were all B Model Mack’s and we lived right across the street from the station which was open 24 hrs.  Nothin like a 3 AM wake up from an air starter....

Here is one of the first PSE intake adaptors but it’s for HI Rise heads.

I would certainly try it first. I went thru the same process with my car. Read quite a few articles and visited webs sites that had answered about the fuel line size debate. My car is 750 hp with 2 750’s and didn’t want to spend money on all the -8 lines and fittings. What finally convinced me to try the stock 3/8” line to the front of the car and -6 to the regulator and fuel log was an article by Don Carlton with his pro stock car. Now I realize pro stock in that era is like S/S today. The jist of the article was Don used a stock fuel line and not a huge electric fuel pump. All his competitors told him he was not getting the full potential out of his engine due to fuel supply. Don finally gave in and spent quite a sum of money to Replace his full system with the large lines and humongous fuel pump. The end result for Don was zero difference...
 My fuel pump is a Holley black past a Fram canister fuel filter thru 3/8 stock fuel line to -6 to fuel regulator -6 to fuel log and - 6 to carbs.  Car in good weather runs 9.70’s @ 138mph. Someday I may try all the big lines just to prove the point. All cars are different so your results may differ- lol

I did what Wowens did. Epoxy primer and i would take them apart.

I use the bottom hole and have had them all over the place as far as pre load. Finally just have them touch spring and half turn of preload with me in the car. Shocks are very firm using Viking D/A. Bias ply 9x29’s Leave at 3750 with clutch setup. As everyone said each car has a different personality due to torque/ hp range, clutch setup, shocks, tire pressures, track etc. etc....

That’s going to be a powerful engine for your Fairlane. It will be fun!!!

I'm guessing 649...

Glad you got it back together, it will  produce some good power
