Rebuilding Heads
I have a '74 2.0L.
Due to a loss of compression on one cylinder, I am going to rebuild/renew the heads.
I am planning to do the following:
1-have machine shop repair damage to what I believe is a burnt valve
2-regrind ALL valve seats
3-replace any damaged valves
4-replace valve guides
5-replace valve springs and keepers with HD springs from PP
6-replace pushrod tubes and seals
7-replace valve cover seals
Are there gaskets between the head and cylinders, or between the cylinders and block? Haven't seen them in PP Catalog.
I'm wondering if shaving the heads to increase compression ratio is advisible and if there is enough material to not compromise the head.
Also, does the Porsche head require a special valve spring tool or will any old valve spring tool be OK?
Like I said, this is what I'm thinking right now. If you have any additions to my list of things to do, let me know. If I forgotten any thing at all, let me know.
Any and all advice is appriciated.
Thanks in advance.
