Default Some more info...

Lets see, answers to questions - Sharroll - ran great first 300 miles, only problems were some leaking headers causing backfire and then the fan belt tossing that started this adventure.

d Ford - amen - been there and done that - actually did it the first time when I was 17 and had just stuck a 302 in my dad's 69 mustang while he was out of town, replacing the straight 6. We all thought it was cool to see the flames and backfiring going on! And despite that, I've managed to do it since then on this car

Just got off the phone with Keith Craft, and here are his answers on some of the questions I posted:

Torque specs:
- Heads - 100 lbs - coat the threads, bolt heads and washers with moly lube

- Intake - 32-34 lbs - coat with copper anti-sieze

- Rocker stands - 42 lbs

- Pre load the hydraulic lifters 1/2 - 3/4 turn after tight. Work your way through the firing order while you do this with the following guidelines: turn the crank until the exhaust valve starts to open - then you can set the intake valve on that cylinder. When the intake valve is closing, you can set the exhaust.

Put some grease or moly on the end of the pushrods to get them to stick in the lifter cups. He's seen problems where the rods moved out of position when installing the rocker assembly and it resulted in bent rod and broken lifter.

Don't have a tray over the lifter valley as it won't fit with hydraulic cam set-up and no need for it regardless. He only uses one when someone wants a completely authentic, iron block and heads original engine build (I guess so one can show people with x-ray vision that there is a tray in there )

No sealant on the head gaskets, just clean the decks really well with lacquer thinner

He's been using 3M Emblem Adhesive spray on the intake gaskets to make them very tacky so they'll stick in place and help seal up the intake. Use gray diesel silicone on the rail area

Just got back from the mad dash south to the Summit Retail store to pick up the gasket set - had to plead my way in the door after arriving at 8:59pm when they close at 9:00 - after a 45 minute drive to get there

So, tomorrow the assembly begins! More to follow......
