Just wondering if anyone here has used this kit. Seems solid although the cam is pretty aggresive. If not the kit, what does everyone think of the TFS super 23's. Anyone using these? Thinking of using this kit on my ZZ4 bottom end.

I wanted to go with the AFR 195 with a 58cc chamber but the price is a bit high. Instead I'm thinking about these. Its good to see they make the power as advertised. Thought about the Edelbrocks but, I've heard the power is a bit lower than they say. Probably going to have to go with a higher stall too, any recomendations?

the guy that ported my heads did some 195 afr heads just previous to mine
both engines were 406's
similar cam profiles
my compression ratio is 11 to 1 the other 406 was 9.75 to 1
all things being close my motor made 53 more h.p

just so you know i did not buy the kit as stated im a big fan of tfs products (heads) you will be hard pressed to hear negative comments about them
