Ultra-reliable "stock" engine?

[Dave_Darling]

The roller rockers sound like an interesting possibility. 911 adjusters are a definite "yes". Spraybars in the rocker box sound interesting, but a really serious PITA. Worth consideration, though!

One problem with the Porsche club(s) is that there is no one set of rules for anything. The Club Race people use one set of rules for their wheel-to-wheel stuff. If I were ambitious, I could make three or possibly four Club Races per year by driving for up to 8 or 12 hours each way. Zone 7 (N. Cal. and a bit of Nev.) uses another set of rules for its time trial and autoX series. Zone 8 (S. Cal.) uses a third set. The Parade autocross (Parade is the national PCA convention) uses a fourth set of rules. The Porsche Owner's Club, who do a lot of big-track stuff, use a fifth set.

Any similarities between any of these sets of rules is purely coincidental.

The rules I am trying to follow are here: http://www.pca-ggr.org/ggrrulebook.html
The classification rules are here: http://www.pca-ggr.org/ggrrulebook.html#_Toc532905425

The class is B-Improved.
