This weekend a friend and I are doing the springs/retainers on his EuroR motor along with Pro2 cams. I happened to talk to another friend actually offering him the Stock R cams and he mentioned that the EuroR/TypeS valves are at a different angle than the Basic H22A and using them would cause premature valvetrain wear. Now if this is the case, is there going to be a problem installing cams meant for a Basic H22A on a EuroR? It was mentioned that the difference in valve angle was 45* & 60*.

 

its hear-say. all H22 heads are the same.

let him know ill take those stockers off his hands

 

So do I assume that the head is the same exact casting and all that sets them apart is the parts installed and hand finished porting?
Anyone here have issues with valvetrain wear while using TypeS/EuroR cams in a Basic H22A head?
I just can't see Honda casting a completely different head with a different valve angle for such a limited production engine such as the TypeS/R. I am assuming that valve angle is not something that can be changed w/o a different casting.
I know the B18C5 head is the same as the other B's except for hand finishing...
As much input as possible would help greatly....

 

you arent going to hear a different answer

Brian.

 

he didnt ask a question regarding the info you supplied. if he had asked, "are there any problems i may run into while installing typeS cams?" then wed be having that discussion.

 

Thanks Brian!!
I don't see US having an issue with Pro2's on the EuroR head with springs/retainers. Its the reverse that WILL cause the problems...

 

now i didnt understand what pocketrockets was saying here?

he says you will have retainer to guide contact at .490 lift, but earlier in the statement he says that typeS cams have .471 lift, yet they still contact? i dont know, kind of confused.

what I grasp from it is there is less room for error when using TypeS cams in a stock H22 head. I guess what it comes down to is I wouldn't use TypeS cams for any reason as I am such a fan of even Skunk stage 1's with a bone stock VT after what it did for my cars. Although my JUNs just own the world!!!!!

are you reffering to the angles cut on the valve seats or the phsical angle that the valve sits in the head? if its just the seat angle it won't matter as long as you have those valves in that head.

as for the retainer clearance some heads are just built differently from others. look in the helms, the tolerance of the valve guide height has a .02" range as well as the height of the valve stem tip to the spring seat. blah blah blah all that means that the spring/retainer clearance could potentially be .04" different from head to head. if you happen to have the head with the lesser clearance combined with type-s cams you might and prolly will run into problems.

 

i would just like to know what the code on the infamous "TypeS" head is.

so if anyone has a "typeS" look at your head, right above the header. there should be a stamp.

That makes all the sense in the world!!
