My buddy called comp cams this morning and they told him the factory integrated seat/seal were fine with the 26918s.... I need one exhaust seal for my 99, ended up with an extra seat and seal when i swapped the cam and springs, and i lost the seal somewhere hope to get my new pushrods in the yukon tomorrow

Ah 918's. They sit just like the LS6's and LS3's using the "hat like" seals. Seems like you have a lot going on project wise!

Helping my buddy with the 5.3 out of the yukon thats going into a bmw, the yukon, my 99 silverado... And at some point my camaro will get a cam and headers and some other stuff.... But i need a break from constantly working on my own stuff!!! Working on the tune in the yukon last few days when ive had time....but also realized i needed longer pushrods!! Bought a set of 7.4s when what i needed was 7.425... I pulled valve cover the other day and measured my preload and am right at if i remember correctly .045 or .055.... I figure out that i need right at a .025 longer pushrod to get me closer to the .080 that i need to quite everything down!!! And at some point soon i need to go back in and figure out which spring seat and seal i didnt change on my 99 when i swapped my springs, which i am fairly certain was on the #4 intake spring when i broke the bolt i was using on the #4 exhaust spring and at 2am i was ready to getvthe spring on the valve i could and go the hell home for the night!! Was also the spring that ended up shooting across my buddies garage and i thought i broke the bolt again...
