So, he offered to make me a couple of hardened steel caps to go over the tensioner pistons in order to put greater tension on the chains. Although my chains seem taught, I think the tension could be tighter. The only other option is to use mechanical chain tensioners - which I am OK with since I would use the race tensioners made by JB Racing. Let's see....
Yeah, I recall him mentioning that to me about the use of hydraulic tensioners in some race engines.

Of course a race engine, that is subject to regular tear downs and scrutiny, can easily get away with the meachanical type.

Being that I'm always into my engine, I'd probably be okay with the mechanical ones too...a lot of shops make a good argument for them.
