I put the down tube onto the lowest head bolt hole on the front face of the head. I just finished my 455 build with Edelbrock RPM round ports.

Looks like it's a go! Picked up the heads from the machinist and he found 2 intake valves slightly bent and 1 exhaust valve slightly bent. Just ordered everything else from butler. headers ,valves misc stuff. cant wait to get this back on the road! likely selling the old dougs headers to help offset the new ones. Plus i'll have a box to ship them in.

Don't assume that fully assembled eheads are ready to run. On mine, the stock valve job from Edelbrock on the exhaust side was .005" OOR which is a lot. The ports were pretty rough too.

Anymore, new heads I buy go straight to the machine shop for a thorough going over checking springs, install height, valve job and valve guide clearances etc....In some cases changing/recutting the valve job if there is a more favorable one that shows gains on the flow bench. I typically pay for some flow bench testing as well because advertised numbers from many of these suppliers are often inflated. |

Ok for my next question...currently my pushrods for the old 96 heads are 5/16x,083 8.750
i want to get the correct length adjustable pushrod checker to make sure my valve train geometry is correct. its seems they come in 1 inch increments. has anyone gone from iron to aluminum and did you need a smaller or longer pushrod? just trying to get an idea of the size i should be looking to get ( adjustable pushrod ). crower lifters and crower roller rockers fwiw. the cam is this one https://butlerperformance.com/i-2936...tegory:1459686 Thanks for the help everyone!

What where you doing with that length push rods when using a late model head like a 96 casting?
The stock length push rod for that set up is 9.145”.

Maybe HR lifters? Just checked a friend's new 455 with RAIV heads with then new Comp HR cartridge and they are 8.70. Yes a big dish!

The same guy that "ported " the 96's i sent you pics of set the valve train up like that. i have to say though the pattern on the valve stem was definably in the center.

Any ideas on the pushrod lengths? shameless bump but its closer to completion. i need to order a pushrod checker.
Or is there a way to ballpark it and get close to knowing what i may need? lots of searches hasnt turned up anything yet.

8.750” to 9.500” should do it easy.

I am running a 9.050" 3/8 pushrod from Trend. They have a perfect pattern on the valve tip.

Yeah, it's not wise to guess, you have to check. No sense putting a temp set in there, waste of money.

There’s too many variables to just go with a length that’s working out in a different motor!
Do it right by checking and take the time to get near max lift while having decent centering of the pattern.

So after a lot of measuring frustration, everything that goes with being a newbie, I came up with 9.050 for my push rod length here are the heads bolted on and the best wear patterns I came up with. I think I’m OK.
