The throat looks undersized a good amount on the intake. The valve job looks very minimum, almost out of the box.

That was my initial thought as well. My VJ's in the past were always 5 angle comp jobs. This is a 3 and nothing exotic, but most on here didn't see it as a big deal and no real magic in 5 angle jobs so I went along.

Anyway of checking throat dia., or are they back together? Were these flowed? Pretty sure you said they were reassembled, and no flow #. Just making sure. There could be 10-30 cfm before the tipover point where the port takes over.

Back together now. Flow numbers I got were 350@.600 and 356@.700 intake. Exhaust was 250@.600 and 254@.700

Have you jumped in head first into the tunnel ram, or is that still just something you're considering?

And when are you expecting to have it running again?

Right but they could be way off under .500 lift. Something for future consideration.

I did a set of SR's that I couldn't get past 325 up top (with my novice short turn hack job)
They went
311 - .500
278 - .400
227 -.300
162 - 200
88 - .100
but with a .650 flat tappet went 9.70 best. Normally 9.80's/90's in a 511ci.

My main argument in the “pros” column of the discussion about the current valve job was...... they had already run solidly into the 9’s as they are.

After seeing them all cleaned up, my argument in the “cons” column is........ there is likely some flow left on the table as they are.

Hard to say for sure how much, or if it would even show up on a time slip.
But I’m sure the flow bench numbers could be improved some.

Its getting T ram next off season, so the Indy 400-3 goes back on with the Thumper 1100 Dominator. It will have a boost in compression to 12.44 or 12.6:1 depending on the gasket thickness of .040 or .045, not sure I want to roll the dice on the .038" quench yet. Looks like it will have an electric water pump as well now since I cant get the new electric fan kit to fit with the belt off the water pump in the way. So it will be going out next time with more compression, electric fans/water pump and open exhaust. Not a good A/B I know, but i'm looking for a number closer to 10'o. Gonna get the carbs in January and the T ram right after. Not sure what I want to do right now as I have enough to get the Holley 750 xp's and the T ram or do I blow all of it on Thumper carbs. Good quality parts are expensive. Decisions Decisions.

Here's what I have from Todd at CWE.
.100-75.1 97.1
.200-164.7 114
.300-222 163.7
.400-278.6 203.8
.500-324.2 232.3
.600-347.8 249.6
.700-356 254.2

my fault, I don't know why I thought these hadn't gone 9's yet. I misunderstood the post. I agree probably not much left then in the heads.

So, you did or did not have the heads re-tested after getting them back this time?

These are the original numbers I got from Todd.

These went 9's on another gentlemans 511 just under 13:1 compression.

Did you ever get the cam specs for the engine your heads were on previously?

You should have plenty of port speed with your engine that big and .650ish cam

What were the combo differences?

No, Todd never got back with me on that.

Best I could tell he had 12.8:1 compression and a small roller .620. I had 11.26:1 and a solid flat tappet 270@50 with .625 lift.

With your change to the compression I would guess 30-40 hp.

I hope so. With run the same single 1100 Dominator this year. A tunnel ram with twin 750's next and possibly a solid roller after that.
