you've got gt40 heads with a cam?

I have the same combo that ryc cukr is using.

I used to have a Bcam with the gt40p heads. It was a nice cam, sounded real good and pulled hard. I know the heads had some kind of machine work dont before I bought them, and the valve seals on them were definately changed, but the retainers were stock, so I cannot confirm whether the springs were the stock explorer springs, but I never had a problem with them (from what I can tell) but it really wasnt the best Idea, I should have changed the springs, 130 bucks is nothing for insuring your motor.

I just ordered a tfs cam and I ordered that same tfs spring kit ryc cukr posted a link for. The kit is real nice, it comes with everything, springs, retainers, shims, seals, keppers, and spring height tool so you can install them yourself. I just finished assembling one of my heads yesterday and it took me about an hour. Theres a forum on corral talking down about the tfs spring kit, and the keepers they use, but I have yet to see someone have a problem with them or destroy a motor using that kit.

I dont know how it runs yet though as it is not put back together, but I am going to assume it will run ALOT better.
