Im about to take my motor and trans out to convert to T56 and just to tidy up my engine bay etc etc.
While the engine is out<i am thinking of replacing the 305 with a 350.I dont at this moment want to go ZZ4 with HSR as I had intended,as the trans swop has proven quite expensive.
My 305 has Jr Sportsman Heads with 1.94"/1.5"valves,58cc chambers,171cc vol and actually uses a 350 head gsaket instead of a 305 gasket.
My question is,can i use these heads and my standard 305 TPI set up(bear in mind mines an 85 with crappy ECU).Will it work if i put bigger injectors in.I realise the TPI might strangle it a bit but at least i would have upgraded to a 350ci.I already have an AFPR,Cold air induction,Headers and 3"SLP exhaust
The other thing is ,would i benefit from 1;6 ratio rockers.I already have a mild cam which was especially for 305/350 TPI.I think i will have to open out the pushrod guide holes to fit these rockers???
What do you think

Thanks
