Mine is a completely standard bottom end. As a road car it will spend very little time at full throttle and not much time at peak revs. I would be a bit wary of taking it only track as I reckon the oil temperature would get too much too. I think will go for forged rods and pistons ultimately rather than the 180 bottom end. Will cost more but at least it's a known engine rather than an unknown used engine.
What miles were only your engine? Doesn't the 180 engine rev to 7500 rpm?

My car doesn't have a standard speedo so I don't know how many miles it had done. I'll ask the previous owner.
Every resource I've looked at states a rev limit of 7300rpm, with peak power around 6800.

While the head was stripped I thought I might as well spend some time DIY port and polishing. This is definitely a mild attempt, basically focusing on knife-edging the split and polishing the walls to an 80 grit finish. No drastic reshaping will take place. I've done tonnes of reading over the last decade about porting and polishing, this will be my first practical attempt. It's started now, so there's no point telling me I shouldn't have done it...

i think mine is set at 7.3k but told it will go to 7.8 but why its still on hydronic lifters so I didn't want to risk it it was also my everyday car at the time.

Been in the new house for 3 months. Spent the last few weeks building a decent work bench,
so that's given me somewhere to work on the cylinder head(s).
I bought a standard EW10J4 cylinder head this week with the plan of dropping the Newman cams into that, putting it on the J4S bottom end and just getting the car running again. I finally unboxed the cams that I'd sent to Newman for checking and refinishing about 9 months ago. Turns out they're 264 400 cams, not 420 as Newman told me over the phone. This means they're 10.1mm lift instead of 10.66. The good news is that this means they spin freely in the EW10J4S cylinder head without any machining, which means I might have bought a J4 head for no reason...
Only problem is I started but haven't finished the port/polish on the J4S head, so I either need to put a load of hours into that (hours I don't really have) or fit the standard J4 head. Decisions, decisions...

IT'S GOT AN ENGINE!! It won't start at the moment but it's turning over.
It's a 180 engine (Not the one I was working on the cylinder head of). Cams have been swapped out for the Newman Cams I had in the old engine. It's been a tricky process figuring out what needs changing or adapting, but I'm nearly there now...
