The way to see if a rocker will fit is just to measure it and fit one on. Just use small block Chevy rockers will most likely work. And valves are valves..... they dont fit specific heads they are just valves. So if your intake is 1.8" big, just get one 1.8" big with the specific length to fit in the head.

do you know what the valve length is off hand. if the valve is like 1.80, i might go with 1.94 * if they fit, and maybe 1.50 or 1.60 exhaust.
i dont have my heads apart, so any help would be great

Off the top of my head no. I would have to take one of the valves off the desk and measure it, I will do it next time I am next to them and when I remember. :P But 1.94 I believe will be too big maybe, that'* like 8-9% larger than stock and I don't believe if will fit because it will overlap into the exhaust valve side and vice versa.

i have put 1.94 valves in a 305 chev head that had 1.72 valves in it.
i did that with a set of 84 trans am 305 HO heads.
what was great, i put them on a 355 i build, and best of all
58CC chambers
took me to almost 11.5:1 compression with flat tops

ok
the 400 sbc is 4.125" bore
350sbc is 4.00 bore
the 305 has the same stroke as a 350 (3.48") but a much smaller bore

i built a 355 for my old drag car. i used the 305HO heads because they were 58cc.
i turned a best of 10.23 sec 1/4 mile time on slicks. but................. my ex told me to get rid of it . i had a 468 that i was building for it, JE pistons, BME alum rods, steel crank , and rect. port alum heads too.
but hind sight is 20/20
should have kept the car and kicked her to the curb then
god i miss that car
