Odessa / Procomp heads--pushrods?

[67Dart273]

Maybe I AM stupid. Saw these.............

http://www.ebay.com/itm/17162334839...em=&sspagename=ADME:X:RTQ:MOTORS:1123&vxp=mtr

Asked the seller if the pushrod holes are compatible with LA roller block, IE they don't look that big, and can they rework them if need be........

and their answer was............

please tell me how big the whole needs to be.. it is pretty large already..

Anybody know anything about these? ARE these holes large enough? Crop from a photo off the sale

Quick look - no. The assumption should be made that you will need to mock up the heads, cam, lifters, rockers, and pushrods and clearance as necessary before final assembly.

That's kinda what I thought. His answer is what troubled me, "they" are supposed to know?

I had to have my Eddy's pushrod holes opened up with a solid flat tappet cam.

Is this with factory based valve gear? Maybe that's what I neglected here. This is not going to run "fat" roller rockers or pushrods. Just stock stuff. If these were factory LA heads off a roller era engine, they "should" bolt on

Isn't Odessa the same as Clearwater? Isn't that the company people were having lots of issues with crappy machine work? Or am I thinking of someone else?

Hughes 1.5 alum. rockers.

My Pro Comps (aka Speedmaster) look to be bigger than the stock LA holes. You'll just have to mock it up and find out. It also depends on the lifters used. some have low seats to help like Hughes ad others.

I suggest getting the heads from Mike at MRL. He did mine, price was good, components installed were of known good quality and the install/ machine work is excellent.

If I read Mike's post correctly it does not include springs, retainers or locks. But call and talk to him. He's the easiest person I've ever talked to.

He has an ad here selling the bare heads and openly quoted one guy for guides, valve and valve job. Call him for the best results, tell him what you want, what your doing ect. He'll steer you right.

Del, what heads do you actually have to work with? (On hand)?

 

[67Dart273]

I have a set of 340 J heads (These were originally on the 340 I put in the old RR back in 73!!!)

I had the guides redone and we just reamed them oversize. Basic valve job. I need to finish up enlarging the pushrod holes.

Still undecided where to go with this.
