302 HO Heads on 351W

1989_351W · 04-24-2002, 07:37 AM

I was wondering, how much would it cost to convert to roller rockers on my 351W heads or could I put the heads off of a 302 HO. I would put larger valves and new springs of course. Is there any difference between the two except for the valve size?

I believe the heads off the 302 will fit. Not sure on the valve train though.

302 heads will fit a 351, the holes for the bolts just need to be drilled out larger.

why don't you just get a set of roller rockers for your 351 heads? are the pedestal or stud mount rockers on there now?

Any idea how much it would cost to convert for roller rockers? It is just the stock heads no guide plates.
