right, i actually take back porting the tb because i would have to get a tune for it, well i actually just dont need that much power, just want to do a swap to a newer gp engine, i know i know, ima want more power later on, but thats not really my goal. need a car point a to point b, but ill keep in mind about porting the heads. are there aftermarket vaccum hoses, mine are so brittle and break easy,
