604 GM Crate Bronze Valve Guides

[RPMLOU]

Hi guys, I have a 604 crate engine coming in that split a valve guide, I want to get a couple guides coming ahead of time. Do anyone of you know what the GM part number is or an equivalent guide pat number is?
Also, who makes these heads for GM? Part number for these too.

Thanks!

if you are trying to keep this "crate legal" bronze valve guides are not permitted

Brad, do you know the guide part number. My dealer was not able to come up with one.

GM does not have a replacement guide----(that's why your dealer couldn't find it)

it is acceptable (in most sanctions) to use a replacement iron guide of the same dimension

we have not had the need to replace many guides but I do have a box somewhere that will have the brand and part# on it that we have used (I will look on Monday and let ya know)----as I recall we found them in a longer length and had to cut them down to spec

be sure to heat the head in an oven for both removal and installation

30-8180 Qualcast is correct for OD & ID but is .150 long, but worried obout being durable enough. Thanks
