I guess the car's about 20 years old, so you would think it's probably sorted out by now.
The small blurb on the engine build says it has standard pistons and standard rocker arms, so I guess there's no stroker in there. And maybe the original pistons? And the weak point on these FEs has always been the original valve train with no end stands. 20 years ago you could pick up a nice set of Erson Roller Rockers for less than a grand. For that nice of a build you would think they would have done some of that. But perhaps they did and it's just not included in the blurb.
