Another Indy intake and head question

[pittsburghracer]

I didn’t want to misdirect the other Indy intake question but does anyone know if Indy heads and Indy intakes have a different intake face angle. Reason I ask is when I tried my moved pushrod Edelbrock heads last year and modified to fit Indy intake no matter what I tried I was sucking oil from the intake valley. Lots of oil

Which Indy Heads.
Did you use the Indy Valley cover?

Sorry small block Indy intake modified to bolt on a set of small block Edelbrock heads I moved the pushrods over on.

Ya I still have two set of 440-1’s that I went 8.40’s@160mph with in my Daytona. I bought 2.250 valves for them but never finished that project because I’ve been pissing around with these dog gone small blocks.

Not to my knowledge. But had a SB Indy intake and while I never used it, it did sit on my block and heads pretty nicely. It sat on top of the block and heads without a gasket and since I had the time, I eye balled it as it sat. Noticing it was looking flush against the heads.

Again, I never actually used it.
Looks can be deceiving.

I bought this intake used so who knows what the first owner did. Another project that needs attention one of these days. I have another one that I ran on my 422 for 5 years so I’ll do some mic’ing one of these days. Hugh’s sent me a “wax kit” to check fit like they show in their tech section.

That’s actually a pretty good way of figuring things out.

 

[MOPARMAGA]

Can't you use an angle finder to figure this out ?

That’s where I’ll be starting but wanted to take the easier way out and ask first.

Yeah I like that option too .

John, I've used shims (like you'd use aligning pump/motor shafts) and feeler gauges to check angles. It won't tell you what angles you're dealing with, but it will tell you if there are different angles. Precision ground washers (ARP head/stud washers) will do the same thing.

With the heads installed, I'll install the intake with shims under the four center bolts. Then stack feeler gauges to measure the gap at the top and the bottom. It's a crude method, but if there is much difference in the angles it'll show.

John when I installed the indy intake on my 360 magnum engine with EQ heads. The intake when on with no problems. But when I had the same intake sent out and had the intake drilled for the LA bolt pattern. I had to have crap load milled off the front and rear pad of the intake, to get the bolt holes to line up. Oops forgot to add thats because I installed a set of trickflow 190CC heads on my 360. Dumbass me should of just sold the indy 360-3 I think thats the intake number and just bought on for the LA engines. I have way to much money in it.
