Hey guys Ive got a quick question Ive had these heads for awhile now they are Trick Flow Specialties TFS-30300006 super 23* 175 aluminum heads, they have the 1.94/1.5 intake/exhaust valves and Im wondering if it was at all possible to have them machined to accept the bigger 2.02/1.6 valves? They are just on a 350 right now and was thinking of getting them worked over or if I should just sell em and grab the 195 heads. All input would be appreciated thanks for time guys and have a good day!

bump bump anybody???

I'd call TrickFlow and ask them. I know there was a thread on here a while back that showed the significant differences between them and a set of factory 305 heads. Among the differences, the valve locations are moved significantly from stock to unshroud the intake (when used on a small-bore 305). Not sure if that would allow a 2.02/1.60 combo to work well, even if you're using them on top of a 4" bore.

okay thanks for that ill give em a shout and what they say
