will this combination work? trick flow stage 1, 1.7 rr, and gt40 heads. what is the max lift for gt40 heads with the stock '89 block and pistons? i think this combo is 530/544. will the piston hit? i know of someone who ran a e303 with 1.7 rockers and gt40p heads, but does anyone know someone running the tfs, 1.7, and gt40 heads? i accidently ordered 1.7 rockers already, but didn't order the cam yet. if i have to i can order the e303 cam, but i would rather use the tfs if possible since i think it is a better cam. also, what is the easiest way to check for clearance. please help, thanks.
