I do not have the proper tool to do the leak down test. If I pull the head before the test is it possible to know if the guide is bad based upon visual inspection? I assume the seals would all be changed given the cost is low.

I am going to proceed under the assumption that the head is coming off either way. I guess that I will be able to address other things at the same time like the chain and rails. Any other items that I should be thinking of at the same time?

What do you think about pulling the head as an assembly with the cam and towers still attached and taking it to the local indy Benz guy? I figure that I can save a lot of labor getting it off, but my tools and skills are limited after that point. He can do the valve job and reassemble the valve train. Is that even possible?

Thanks
